'''Date:''' 23 October 2013.

'''Abstract:''' The Audubon 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 Audubon Core term, including a documentation name, a specified URI, a recommended English label for user interfaces, a definition, and some ancillary notes.  The version shown here has been adopted by Biodiversity Information Standards / TDWG at the general meeting in October 2013. This is a normative document and the definition may not be changed without due process. A second version of Audubon Core, [[Audubon Core Development]], will reflect the ongoing documentation changes and draft enhancements.

An Audubon Core (AC) record is a description of a multimedia resource using the AC vocabularies. Two kinds of terms are specified by this document: those terms which describe representation-independent aspects of the media and those which describe representation-dependent aspects. Most terms are representation-independent, referring to an "abstract multimedia resource". One such term, ''hasServiceAccessPoint'', refers to or contains representation-dependent service access point metadata describing a digital representation of the abstract multimedia resource. 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).

{{ACHeader | Borrowed Vocabulary | 2 }}

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. Common such usage for abbreviations and namespace prefixes are Darwin Core (DwC, dwc:), the Dublin Core Metadata Initiative(DC, comprising two namespaces, with prefixes dc: and dcterms:), Adobe XMP (XMP, xmp:), International Press and Telecommunications Council (IPTC, Iptc4xmpExt:), the Exchangeable Image File Format (EXIF, exif:) and the TDWG Ontologies Natural History Collection class (NCD, ncd:). Hypertext links in the term table entries will bring the reader to appropriate documentation of those organizations.

{{ACHeader | Namespaces, Prefixes and Term Names | 2 }}

The namespace of terms borrowed from other vocabularies is that of the original. The namespace of de novo AC terms is <nowiki>http://rs.tdwg.org/ac/terms/</nowiki>. 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|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 [http://dublincore.org/ Dublin Core Metadata Initiative (DCMI)], provide version 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 '''[http://wiki.dublincore.org/index.php/FAQ/DC_and_DCTERMS_Namespaces 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|dc:type]] and [[#dcterms:type|dcterms:type]]. When such a pair allows repeated instances (e.g. as for [[#dc:source|dc:source]] and [[#dcterms:source|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 [[Audubon Core Structure#Multiplicity/Cardinality|Multiplicity and Cardinality]].

{{#vardefine:defaultPrefix| ac}}
{{ACHeader | Layers | 2 }}

The term set consists of two ''Layers'', numbered ''1'' and ''2''. The former comprise the central terms, likely to be meaningful for most media, even though only a few are mandatory. Implementers of AC representations should provide for at least Layer 1 if possible, and application writers should provide for robust treatment of Layer 1 terms, if only by ignoring them. Layer 2 terms are more likely to be useful for particular kinds of media or for applications requiring highly detailed resource descriptions. Each term description below indicates the Layer to which the term belongs.

{{ACHeader | Literal- vs. URI-valued Terms | 2}}

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.

 | 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”).

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).

All geography terms from the DarwinCore [http://rs.tdwg.org/dwc/2009-12-07/terms/#dcterms version of 9 Dec 2009] are deemed included in the Core Layer. Specifically, this includes exactly those which are declared by DarwinCore to be in DarwinCore Class [http://rs.tdwg.org/dwc/2009-12-07/terms/#dcterms:Location Location].  Note that [http://rs.tdwg.org/dwc/terms/locality  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 (MWG 2010)<ref name="MWG2010">(MWG 2010)  Metadata Working Group Guidelines for Handling Image Metadata, Version 2.0,November 2010 http://www.metadataworkinggroup.org/pdf/mwg_guidance.pdf</ref> 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).

 | Label = Identification Qualifier
 | Defined by = {{NS dwctermsDoc | identificationQualifier}}
 | Definition = 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|Scientific Taxon Name]]. 
 | Layer = 1
 | Repeatable = Yes
 | Notes = Splitting identification qualification and [[#Scientific_Taxon_Name|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_Name|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|Scientific Taxon Name]].

For discussion of Darwin Core usage see [http://code.google.com/p/darwincore/wiki/Identification here].

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.

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.

Annotating whether and how a resource has been modified or edited significantly in ways that are not immediately obvious to, or expected by, consumers is of special significance. 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.) If it is only known that significant modifications were made, but no details are known, a general statement like “Media may have been manipulated to improve appearance” may be appropriate.

* Lower Quality: Service Access Point provides a lower quality version of the media resource, suitable e. g. for web sites.
* Medium Quality: Service Access Point provides a medium quality version of the media resource, e. g. shortened in duration, or reduced size, using lower resolution or higher compression causing moderate artifacts.
* Good Quality: Service Access Point provides a good quality version of the media resource intended for resources displayed as primary information; e. g. an image between 800 and 1600 px in width or height.
