Abstract: The Audiovisual Core is a set of vocabularies designed to represent metadata for biodiversity multimedia resources and collections. It aims to represent information that will help to determine whether a particular resource or collection will be fit for some particular biodiversity science application before acquiring the media. Among others, the vocabularies address such concerns as the management of the media and collections, descriptions of their content, their taxonomic, geographic, and temporal coverage, and the appropriate ways to retrieve, attribute and reproduce them. This document contains a list of attributes of each Audiovisual Core term, including a documentation name, a specified URI, a recommended English label for user interfaces, a definition, and some ancillary notes. This document contains normative content that may not be changed without due process.

1. Введение

There are a number of documents included in the Audiovisual Core Standard. This document provides details about the terms included in the 2023-09-05 version of the Audiovisual Core vocabulary. The Audiovisual Core Introduction document provides a brief introduction to the Audiovisual Core Standard. For information about the structure of Audiovisual Core, see the Audiovisual Core Structure document. For a more detailed guide to the use of Audiovisual Core, see the Audiovisual Core Guide document.

1.1 Статус содержания документа

Sections 1.3 through 5 are normative, except for Table 1. In Section 7 and its subparts, the values of the Normative URI, Definition, Required, and Repeatable are normative. The value of Usage (if it exists for a given term) is normative in that it specifies how a borrowed term should be used as part of Audiovisual Core. The values of Term Name is non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. Labels and the values of all other properties (such as notes) are non-normative.

1.2 Ключевые слова RFC 2119

Ключевые слова «MUST», «MUST NOT», «REQUIRED», «SHALL», «SHALL NOT», «SHOULD», «SHOULD NOT», «RECOMMENDED», «MAY» и «OPTIONAL» в настоящем документе должны толковаться так, как это описано в BCP 14 [RFC 2119] и [RFC 8174] только тогда, когда они написаны заглавными буквами.

1.3 Categories of terms

An Audiovisual Core (AC) record is a description of a multimedia resource using the AC vocabularies. Three kinds of terms are specified by this document: those terms which describe representation-independent aspects of the media, those which describe representation-dependent aspects, and those that designate specified parts of the media item. Most terms are representation-independent, referring to an “abstract multimedia resource”. One such term, ac:hasServiceAccessPoint, refers to or contains representation-dependent service access point metadata describing a digital representation of the abstract multimedia resource (an instance of the ac:ServiceAccessPoint class). These metadata describe such things as a web address at which a digital representation can be retrieved, and the format, extent, or licenses that describe a particular such representation. A multimedia resource may provide several access points for different representations (e.g., different resolutions). The resource may also be linked to one or more Regions of Interest (ROI) that define parts within the media item (instances of the ac:RegionOfInterest class).

2 Borrowed Vocabulary

When terms are borrowed from other vocabularies, AC uses the URIs, common abbreviations, and namespace prefixes in use in those vocabularies. The URIs are normative, but abbreviations and namespace prefixes have no impact except as an aid to reading the documentation.

Table 1. Vocabularies from which terms have been borrowed (non-normative)

Note: URIs for terms in most of these namespaces do not dereference to anything. The authoritative documentation can be obtained by clicking on the vocabulary names in the table.

3 Namespaces, Prefixes and Term Names

The namespace of terms borrowed from other vocabularies is that of the original. The namespace of de novo AC terms is http://rs.tdwg.org/ac/terms/. In the table of terms, each term entry has a row with the term name. This term name is generally an “unqualified name” preceded by a widely accepted prefix designating an abbreviation for the namespace It is RECOMMENDED that implementers who need a namespace prefix for the AC namespace use ac. In this web document, hovering over a term in the Index By Term Name list below will reveal a complete URL that can be used in other web documents to link to this document’s treatment of that term, even if it is from a borrowed vocabulary. It is very important to note that some vocabularies, e.g those of the Dublin Core Metadata Initiative (DCMI), provide versions of the same term in two different namespaces, one providing for string values and one providing for URIs, even where that separation is simply a recommendation, not a mandate. See this DCMI wiki entry on this topic. For vocabularies where such a practice is in place, we often follow it and signal a reference in the Notes of our term descriptions to the sister version of the term. An example is the pair dc:type and dcterms:type. When such a pair allows repeated instances (e.g. as for dc:source and dcterms:source), particular care may be required in some implementations of AC, because some implementations may not provide enough structure to clearly state the association between the members of a pair in the case of multiple values of each. This is a special case of the issue treated in the normative material on Multiplicity and Cardinality in the Audiovisual Core Structure document.

4 Layers

(The Audiovisual Core layer property has been deprecated as of 2020-01-27)

5 Literal- vs. URI-valued Terms

Some terms have two versions, one expecting a string literal value and the other a URI. In these circumstances, the version expecting a string is named with the suffix “Literal”, e.g. ac:metadataLanguageLiteral. In such cases, both forms MAY be provided, but care should be taken to ensure that the uses reflect the same intent. In case of ambiguity, the URI version prevails. All terms, including those whether or not with a specific “Literal” suffix, specify in their definition whether the required values are strings or URIs.

IRI версии термина	http://dublincore.org/usage/terms/history/#available-003
Метка	Date Available
	required: No -- repeatable: No
Определение	Date (often a range) that the resource became or will become available.
Использование	The date (often a range) that the resource became or will become available. The date and time MUST comply with the World Wide Web Consortium (W3C) datetime practice, https://www.w3.org/TR/NOTE-datetime, which requires that date and time representation correspond to ISO 8601:1998, but with year fields always comprising 4 digits. This makes datetime records compliant with 8601:2004, https://www.iso.org/standard/40874.html. AC datetime values MAY also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus ("forward slash", '/').
notes	A use case is the harvesting of metadata published before the media are available, which are pending a formal publication elsewhere. One important example is the case of metadata that documents an occurrence, which metadata harvesters might exploit without use of the media. See also the wikipedia IS0 8601 entry, https://en.wikipedia.org/wiki/ISO_8601, for further explanation and examples.

There is a separate item for Reviewer Comments, which is defined more as an expert-level review. Implementers or communities of practice might establish conventions about the meaning of the absence of a commenter, but this specification is silent on that matter.

	required: No -- repeatable: Yes
Определение	In a chosen serialization (RDF, XML Schema, etc.) the potentially multiple service access points (e.g., for different resolutions of an image) might be provided in a referenced or in a nested object. This property identifies one such access point. That is, each of potentially multiple values of hasServiceAccessPoint identifies a set of representation-dependent metadata using the properties defined under the Service Access Point Vocabulary section of the Audiovisual Core Term List document.
notes	Some serializations may flatten the model of service-access points by (a) dropping ac:hasServiceAccessPoint, ac:variant and ac:variantLiteral, (b) repeating properties from the Service Access Point Vocabulary and prefixing them with values of ac:variantLiteral. If such a flat serialization is necessary for services, we recommend to select from among term names of the form "AB" where "A" is one of thumbnail, trailer, lowerQuality, mediumQuality, goodQuality, bestQuality, offline and "B" is one of AccessURI, Format, Extent, FurtherInformationURL, LicensingException, ServiceExpectation (example: thumbnailAccessURI). Implementers in specific constraint languages such as XML Schema or RDF may wish to make Access URI and perhaps dcterms:format mandatory on instances of the service access point.

	required: Yes -- repeatable: No
Определение	The URI of the language of description and other metadata (but not necessarily of the image itself) , from the ISO639-2 list of URIs for ISO 3-letter language codes, http://id.loc.gov/vocabulary/iso639-2.
Использование	At least one of ac:metadataLanguage and ac:metadataLanguageLiteral MUST be supplied but, when feasible, supplying both might make the metadata more widely useful. They must specify the same language. In case of ambiguity, ac:metadataLanguage prevails.
notes	This is NOT dcterms:language, which is about the resource, not the metadata. Metadata Language is deliberately single-valued, imposing on unstructured serializations a requirement that multi-lingual metadata be represented as separate, complete, metadata records. Audiovisual Core requires that each record also contains the language-neutral terms. In the absence of this requirement, metadata consumers would need to know which terms are language-neutral and merge these terms from all provided metadataLanguages into a single record. Metadata consumers may re-combine the information based on the dcterms:identifier that identifies the multimedia resource. Nothing in this document would, however, prevent an implementer, e. g. of an XML-Schema representation, from providing a fully hierarchical schema in which language neutral terms occur only a single time, and only the language-specific terms are repeated in a way that unambigously relates them to a metadata language. In RDF it may be a simple repetition of plain literals associated with a language (e.g., xml:lang attribute in RDF/XML). The language attribute would then be required in Audiovisual Core and would replace ac:metadataLanguage.

Метка	Title
	required: No -- repeatable: No
Определение	A name given to the resource.
Использование	Concise title, name, or brief descriptive label of institution, resource collection, or individual resource. This field SHOULD include the complete title with all the subtitles, if any.
notes	It is strongly suggested to provide a title. The title facilitates interactions with humans: e.g., it could be used as display text of hyperlinks or to provide a choice of images in a pick list. The title is therefore highly useful and an effort should be made to provide it where it is not already available. When the resource is a collection without an institutional or official name, but with a thematic content, a descriptive title, e. g. "Urban Ants of New England," would be suitable. In individual media resources depicting taxa, the scientific name or names of taxa often form a good title. Common names in addition to or instead of scientific names are also acceptable. Indications of action or roles captured by the media resource, such as predatory acts, are desirable ("Rattlesnake eating deer mouse", "Pollinators of California Native Plants").

Определение	Характер или жанр ресурса.
Использование	The value of dc:type SHOULD be a term name of any term from the DCMI Type Vocabulary, https://www.dublincore.org/specifications/dublin-core/dcmi-terms/#section-7 RECOMMENDED term names for media items are "Collection", "StillImage", "Sound", "MovingImage", "InteractiveResource", and "Text". A Collection MUST be given a value of "Collection". Following the DC recommendations at http://purl.org/dc/dcmitype/Text, images of text SHOULD be given a value of "Text" for dc:type. A value for at least one of dc:type and dcterms:type MUST be supplied in an Audiovisual Core record but when feasible, supplying both can make the metadata more widely useful. The values of dc:type and dcterms:type SHOULD designate the same type, but in case of ambiguity dcterms:type prevails.
notes	If the resource is a Collection, this term does not identify what types of objects it may contain. See also the entry for dcterms:type in the Audiovisual Core term list document and see the DCMI FAQ on DC and DCTERMS Namespaces, https://web.archive.org/web/20171126043657/https://github.com/dcmi/repository/blob/master/mediawiki_wiki/FAQ/DC_and_DCTERMS_Namespaces.md, for discussion of the rationale for terms in two namespaces.

Использование	The value of dcterms:type SHOULD be an IRI of any term from the DCMI Type Vocabulary, https://www.dublincore.org/specifications/dublin-core/dcmi-terms/#section-7 . In text-based systems (e.g. spreadsheets) the value MUST be an IRI with an unabbreviated namespace. Machine-readable systems MAY use any form of the IRI (e.g. compact URIs; CURIEs) that can be determined to be equivalent to the unabbreviated IRI. RECOMMENDED values for media items are those IRIs whose term names are "Collection", "StillImage", "Sound", "MovingImage", "InteractiveResource", and "Text". A Collection MUST be given a value of http://purl.org/dc/dcmitype/Collection.

In that case, omit or leave empty xmpRights:Owner, and put 'Public Domain' in the Copyright Statement (dc:rights). Note: Audiovisual Core guidelines on value format are less restrictive than is specified in the IPTC guidelines.
notes	Some providers use dc:publisher for this purpose, but it seems doubtful that the publisher is by necessity the copyright owner. 'Public Domain' is not an appropriate value because it denotes something that is not under copyright. Except for 'Public Domain' resources, it is strongly urged that this field be supplied.

notes	If the resource was digitized from a non-digital resource, or was also previously published in a digital or printed publication, this describes the original. If a string is required for this, use dc:source. Do not put generally "related" publications in here. A URI that can be resolved and dereferenced to provide a description of the source resource may also be used here. For example, "http://www.loc.gov/pictures/item/fsa1998021539/PP/" is the address of a web page that provides a description the original negative of a famous picture by the photographer Dorothea Lange and so would be an appropriate value of dcterms:source.

Метка	License Terms
	required: No -- repeatable: No
Определение	A collection of text instructions on how a resource can be legally used, given in a variety of languages.
Использование	The license statement defining how resources might be used. Information on a collection applies to all contained objects unless the object has a different statement. Where different quality variants (e. g. different resolutions of images) are published under different licenses, the AC term "Licensing Exception Statement" supports variant-specific licenses. Note that the medium or low resolution levels of the same image might be available under open access licenses.
notes	Example: "Available under Creative Commons BY-SA 3.0 license". This also describes the commercial availability of items. Buying an identification tool or media resource is essentially the purchase of an individual license. Examples for such License statements: "Available through bookstores" for a commercially published CD, and "Individual licenses available for purchase" for a high-resolution image. In general, this term determines the default licensing for the media. License terms specific to variants or representations of the media resource (e.g., different resolutions) are dealt within the section on Service Access Point Vocabulary

AC-recommended vocabularies are preferred and MAY be unqualified literals (not a full URI). For terms from other vocabularies either a precise URI SHOULD be used, or, as long as all unqualified terms in all vocabularies are unique, metadata SHOULD provide the source vocabularies using the Subject Category Vocabulary term.

notes	Recommended sets include: the NASA Global Change Master Directory (GCMD; http://gcmd.nasa.gov/), Subject Categories defined in Key to Nature (K2N; http://www.keytonature.eu/wiki/Subject_Category), the BioComplexity Thesaurus; https://www2.usgs.gov/core_science_systems/csas/biocomplexity_thesaurus/, the Description Type GBIF Vocabulary; http://rs.gbif.org/vocabulary/gbif/description_type.xml, the TDWG Species Profile Model; http://rs.tdwg.org/ontology/voc/SPMInfoItems.rdf, the Plinian Core; https://github.com/tdwg/PlinianCore/wiki, the European Environmental Agency GEneral Multilingual Environmental Thesaurus (GEMET; http://www.eionet.europa.eu/gemet), and the Long Term Ecological Research Network Controlled Vocabulary (LTER; http://vocab.lternet.edu/). The vocabulary may include major taxonomic groups (such as "vertebrates" or "fungi") or ecosystem terms ("savannah", "temperate rain forest", "forest fires", "aquatic vertebrates"). Other formal classifications (published in print or online) such as habitat, fuel, invasive species, agroproductivity, fisheries, migratory species etc. are also suitable.

Метка	Description
	required: No -- repeatable: No
Определение	An account of the resource.
Использование	Description of collection or individual resource, containing the Who, What, When, Where and Why as free-form text.
notes	This property optionally allows the presentation of detailed information and will in most cases be shown together with the resource title. If both a description and a caption are present in the metadata, a description is typically displayed instead of the resource, whereas a caption is displayed together with the resource. The description should aim to be a good proxy for the underlying media resource in cases where only text can be shown, whereas the caption may only make sense when shown together with the media. Thus, in HTML it would be appropriate to use dcterms:description values for alt attributes in img elements. Often only one of description or caption is present; choose the term most appropriate for your metadata. It is the role of implementers of an AC concrete representation (e.g., an XML Schema, an RDF representation, etc.) to decide and document how formatting advice will be represented in descriptions serialized according to such representations.

7.5 Geography Vocabulary

Note that dwc:locality may be used, but as applied to media this term may be ambiguous as to whether it applies to the location depicted or the location at which the media was created. When disambiguating information is available, it is better to use the terms Location Shown and Location Created. The latter is in the Resource Creation Vocabulary.

Location Created and Location Shown are separated in the current version of IPTC, and the Metadata Working Group (Metadata Working Group Guidelines for Handling Image Metadata, Version 2.0, November 2010) also recommends this. We follow this below in order to support the expected future increase of automatic GPS-based coordinate recording. As a special case, the AC group recommends to change the semantics of Location Shown in the case of biodiversity specimens, where the original location may differ from the current location at which the specimen is held in a collection. In this case, Location Shown should exclusively refer to the location where a specimen was originally collected (gathering or sampling location). Use Location Created to express the location where the resource was created (a specimen was digitized).

7.6 Temporal Coverage Vocabulary

term_name xmp:CreateDate
IRI термина	http://ns.adobe.com/xap/1.0/CreateDate
Изменено	2021-10-05
Метка	Original Date and Time
	required: No -- repeatable: No
Определение	The date and time the resource was created. For a digital file, this need not match a file-system creation time. For a freshly created resource, it should be close to that time, modulo the time taken to write the file. Later file transfer, copying, and so on, can make the file-system time arbitrarily different.
Использование	The date of the creation of the original resource from which the digital media was derived or created. The date and time MUST comply with the World Wide Web Consortium (W3C) datetime practice, https://www.w3.org/TR/NOTE-datetime, which requires that date and time representation correspond to ISO 8601:1998, but with year fields always comprising 4 digits. This makes datetime records compliant with 8601:2004, https://www.iso.org/standard/40874.html. AC datetime values MAY also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus ("forward slash", '/'). When applied to a media resource with temporal extent such as audio or video, this property indicates the startTime of the recording.
notes	What constitutes "original" is determined by the metadata author. Example: Digitization of a photographic slide of a map would normally give the date at which the map was created; however a photographic work of art including the same map as its content may give the date of the original photographic exposure. Imprecise or unknown dates can be represented as ISO dates or ranges. Compare also Date and Time Digitized in the Resource Creation Vocabulary. See also the wikipedia IS0 8601 entry, https://en.wikipedia.org/wiki/ISO_8601, for further explanation and examples.

Метка	Temporal Coverage
	required: No -- repeatable: No
Определение	Temporal characteristics of the resource.
Использование	The coverage (extent or scope) of the content of the resource. Temporal coverage will typically include temporal period (a period label, date, or date range) to which the subjects of the media or media collection relate. If dates are mentioned, they SHOULD follow ISO 8601. When the resource is a Collection, this refers to the temporal coverage of the collection. Following dcterms:temporal, the value MUST be a URI.
notes	See the DCMI User Guide dcterms:temporal entry, https://github.com/dcmi/repository/blob/master/mediawiki_wiki/User_Guide/Publishing_Metadata.md#dctermstemporal, for an example. dc:coverage may be used for string values of temporal coverage, but use the Geography Vocabulary for geographic coverage. String examples for use with dc:coverage include "Jurassic", "Elizabethan", "Spring, 1957". 2008-01-01/2008-06-30. If the resource is video or audio, it refers to the time span, if any, depicted by the resource. For live-media this is closely related to Original Date and Time (Example: the time depicted by a time-lapse video file of organism development), but for media with fictional content it is not.

Определение	A brief phrase or a standard term ("cf.", "aff.") to express the determiner's doubts about the Identification.
Использование	A brief phrase or a standard abbreviation ("cf. genus", "cf. species", "cf. var.", "aff. species", etc.) to express the determiner's doubts with respect to a specified taxonomic rank about the identification given in Scientific Taxon Name.
notes	Splitting identification qualification and Scientific Taxon Name into separate fields is recommended practice in cases where only a single taxon name is available, or if the exchange format is able to keep relations between multiple names and identification qualifiers. Where the exchange format only supports simple multiplicities, a media item with multiple Scientific Taxon Names, some with, some without identification qualifiers, may have to be transferred with "cf." or "aff." qualifiers remaining embedded in the Scientific Taxon Name. Example: For the determinations "cf. Fusarium oxysporum f. sp. palmarum", "Fusarium cf. oxysporum f. sp. palmarum", "Fusarium oxysporum cf. f. sp. palmarum" the Scientific Taxon Name would always be "Fusarium oxysporum f. sp. palmarum", with Identification Qualifier "cf. genus", "cf. species" and "cf. f.sp.", respectively. In most cases only the lowest taxon is in doubt, but cases exist where good reasons exist to suspect a specific or even infraspecific determination, without having a save generic identification.

Метка	Scientific Taxon Name
	required: No -- repeatable: Yes
Определение	The full scientific name, with authorship and date information if known. When forming part of an Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term.
Использование	Scientific names of taxa represented in the media resource (with date and name authorship information if available) of the lowest level taxonomic rank that can be applied.
notes	The Scientific Taxon Name may possibly be of a higher rank, e.g., a genus or family name, if this is the most specific identification available. Where multiple taxa are the subject of the media item, multiple names may be given. If possible, add this information here even if the title or caption of the resource already contains scientific taxon names. Where the list of scientific taxon names is impractically large (e.g., media collections or identification tools), the number of taxa should be given in Taxon Count (see below). If possible, avoid repeating the Taxonomic Coverage here. Do not use abbreviated Genus names ("P. vulgaris"). It is recommended to provide author citation to scientific names, to avoid ambiguities in the presence of homonyms (the same name created by different authors for different taxa). Identifier qualifications should be supplied in the Identification Qualifier term rather than here (i. e. "Abies cf. alba" is deprecated, to be replaced with Scientific Taxon Name = "Abies alba" and Identification Qualifier = "cf. species").

Метка	Taxon Count
	required: No -- repeatable: No
Определение	An exact or estimated number of taxa at the lowest applicable taxon rank (usually species or infraspecific) represented by the media resource (item or collection).
Использование	The count SHOULD contain only the taxa covered fully or primarily by the resource. This SHOULD be a single integer number.
notes	Primarily intended for resource collections and singular resources dealing with sets of taxa (e. g., identification tools, videos). It is recommended to give an exact or estimated number of specific taxa when a complete list of taxa is not available or practical. For a taxon page and most images this will be "1", i. e. other taxa mentioned on the side or in the background should not be counted. However, sometimes a resource may illustrate an ecological or behavioral entity with multiple species, e. g., a host-pathogen interaction; taxon count would then indicate the known number of species in this interaction. Leave the field empty if you cannot estimate the information (do not enter 0). Additional taxon counts at higher levels (e. g. how many families are covered by a digital Fauna) should be given verbatim in the resource description, not here.

	required: No -- repeatable: No
Определение	A higher taxon (e. g., a genus, family, or order) at the level of the genus or higher, that covers all taxa that are the primary subject of the resource (which may be a media item or a collection).
notes	Example: Where the subject of an image is several species of ducks with trees visible in the background, Taxon Coverage would still be Anatidae (and not Biota). Example: "Aves" for a bird key or a bird image collection. Do not add a rank ("Class Aves") in this field. Note that this somewhat expands the usage of ncd:taxonCoverage which, however has not yet been adopted by TDWG, and which specifies at the Family level or higher. For collections it is recommended to follow ncd:taxonCoverage to avoid conflicts between an AC record and a record arising from use of the un-adopted NCD. If the resource contains a single taxon, this should be placed in Scientific Taxon Name. In this case Taxon Coverage may be left empty, but if not, care should be taken that the entries do not conflict. Example: If Scientific Taxon Name is Quercus alba then Taxon Coverage, if provided at all, should be Quercus.

	required: No -- repeatable: No
Определение	Date the first digital version was created, if different from Original Date and Time found in the Temporal Coverage Vocabulary.
Использование	The date and time MUST comply with the World Wide Web Consortium (W3C) datetime practice, https://www.w3.org/TR/NOTE-datetime, which requires that date and time representation correspond to ISO 8601:1998, but with year fields always comprising 4 digits. This makes datetime records compliant with 8601:2004, https://www.iso.org/standard/40874.html. AC datetime values MAY also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus ("forward slash", '/'). Use the international (ISO/xml) format yyyy-mm-ddThh:mm (e. g. "2007-12-31" or "2007-12-31T14:59"). Where available, timezone information SHOULD be added.
notes	This is often not the media creation or modification date. For example, if photographic prints have been scanned, the date of that scanning is what this term carries, but Original Date and Time is that depicted in the print. In the case of digital images containing EXIF, whereas the EXIF capture date does not contain time zone information, but EXIF GPSDateStamp and GPSTimeStamp may be relevant as these include time-zone information. See also Metadata Working Group Guidelines for Handling Image Metadata, Version 2.0 (November 2010), https://web.archive.org/web/20180919181934/http://www.metadataworkinggroup.org/pdf/mwg_guidance.pdf, which has best practice advice on handling time-zone-less EXIF date/time data.

Examples for images are: Removing a distracting twig from a picture, moving an object to a different surrounding, changing the color in parts of the image, or blurring the background of an image. Modifications that are standard practice and expected or obvious are not necessary to document; examples of such practices include changing resolution, cropping, minor sharpening or overall color correction, and clearly perceptible modifications (e.g., addition of arrows or labels, or the placement of multiple pictures into a table.)

notes	Derivation of one resource from another is of special interest for identification tools (e. g. a key from an unpublished data set, as in FRIDA, or a PDA key from a PC or web key) or web services (e. g. a name synonymization service being derived from a specific data set). It may very rarely also be known where one image or sound recording is derived from another (but compare the separate mechanism to be used for quality/resolution levels). Can be repeated if a montage of images.

7.10 Service Access Point Vocabulary

These terms are representation-dependent metadata, referring to specific digital representations of a resource (e.g., a specific resolution, quality, or format). They are used within whatever a particular AC implementation assigns to the value of ac:hasServiceAccessPoint, whose label is simply “Service Access Point.” Note that it is possible for an implementation to use syntactic conventions that avoid direct use of ac:hasServiceAccessPoint, as illustrated in the final example in the section Multiplicity/Cardinality in the Audiovisual Core Structure document.

Human-readable information about the Controlled Vocabulary for format is at http://rs.tdwg.org/ac/doc/format/ .
notes	This term can be used to describe offline digital content. In cases where the provided Service Access Point URL includes a standard file extension from which the format can be inferred, it is permissible to not provide a value for this property. See also the entry for dcterms:format in the Audiovisual Core term list document and see the DCMI FAQ on DC and DCTERMS Namespaces, https://web.archive.org/web/20171126043657/https://github.com/dcmi/repository/blob/master/mediawiki_wiki/FAQ/DC_and_DCTERMS_Namespaces.md, for discussion of the rationale for terms in two namespaces. It is best practice to use dcterms:format instead of dc:format whenever practical. Normal practice is to use the same Label if both are provided. Labels have no effect on information discovery and are only suggestions.

7.11 Region of Interest Vocabulary

Regions of Interest (ROI) designate specific parts of media items. Features within these regions can be taxonomically identified or linked to occurrence records. ROI metadata may also be used to generate annotations of the media item or to facilitate display or highlighting of specific parts.

Currently spatial ROIs are limited to two dimensions and can only be defined by rectangles or arcs (including circles). The terms in this group are not repeatable within a single ROI instance, although a media item may be linked to more than one ROI by the ac:hasROI property.

For examples showing how to use these terms, see the ROI Recipes page.
