Darwin Core Data Package - Quick Reference Guide
Introduction
This guide is provided to assist users to understand the structure and content of Darwin Core Data Packages. The Darwin Core Data Package (DwC-DP) is an implementation of the Darwin Core Conceptual Model following the specifications in the Darwin Core Data Package Guide.
This Quick Reference Guide is distinct from the classic Darwin Core Quick Reference Guide in that this guide contains information beyond the simple term definitions. It includes all the information about how to use Darwin Core in the context of a Darwin Core Data Package. That means it includes data types, value constraints, table relationship constraints and repeats these everywhere in the structure that a given term is found. This guide makes reference to numerous terms borrowed from standard vocabularies, both internal and external to TDWG, other than the Darwin Core. In general these terms are not in the classical Darwin Core reference guide nor in the Darwin Core list of terms as they are externally managed and reused in this context.DwC-DP is implemented using tables, most of which correspond directly to classes in Darwin Core. The sidebar at the right provides quick access to table definitions, and the definitions of available fields for each table. For an overview of the tables and their relationships, see the Visual Summary. Supplementary to this document is the Darwin Core Data Package Relationship Explorer, which provides an interactive visual guide to the relationships between tables in DwC-DP.

Organism Interaction
Identifier: http://rs.tdwg.org/dwc/dwc-dp/organism-interaction
Description: An interaction between two dwc:Organisms during a dwc:Event.
Comments: Supports only primary observed interactions, not habitual or derived taxon-level interactions. Pairwise interactions must be used to represent multi-organism interactions. When possible, typify the action rather than the state from which an action is inferred, with the actor as the subject dwc:Occurrence and the acted-upon as the related dwc:Occurrence. Only one direction of a two-way interaction is necessary, though both are permissible as distinct OrganismInteractions with distint subject dwc:Occurrences.

| Description | A list (concatenated and separated) of taxa reported during a dwc:Event that are outside of the target taxonomic scope (the combination of eco:targetTaxonomicScope and eco:excludedTaxonomicScope). |
| Comments | This term is meant to allow the full list of taxa that are considered outside of the taxonomic scope and yet were reported in the dataset to be shared. This term is relevant only if a target taxonomic scope is declared and eco:hasNonTargetTaxa is ‘true’. Taxonomic scope is based on the combination of eco:targetTaxonomicScope and eco:excludedTaxonomicScope. Non-target taxa (in some disciplines called “bycatch”) can be reported at any taxonomic level. Recommended best practice is to separate multiple values in a list with space vertical bar space (` | `). This term has an equivalent in the dwciri: namespace that allows only an IRI as a value, whereas this term allows for any string literal value. |

(from secundum, meaning "according to"). For taxa that result from identifications, a reference to the keys, monographs, experts and other sources should be given. |
| Comments | This term provides context to the dwc:scientificName. Together with the dwc:scientificName, separated by `sensu` or `sec.`, it forms the taxon concept label, which may be seen as having the same relationship to dwc:taxonConceptID as, for example, dwc:acceptedNameUsage has to dwc:acceptedNameUsageID. When not provided, in Taxon Core data sets the dwc:nameAccordingTo can be taken to be the data set. In this case the data set mostly provides sufficient context to infer the delimitation of the taxon and its relationship with other taxa. In Occurrence Core data sets, when not provided, dwc:nameAccordingTo can be an underlying taxonomy of the data set, e.g. Plants of the World Online (http://powo.science.kew.org/) for vascular plant records in iNaturalist (in which case it should be provided), or, which is the case for most dwc:PreservedSpecimen data sets, the dwc:Identification, in which case there is no further context. |

| Table: | Identification Taxon |
| Description | Part of the name of a cultivar, cultivar group or grex that follows a dwc:scientificName. |
| Comments | According to the Rules of the Cultivated Plant Code, a cultivar name consists of a botanical name followed by a cultivar epithet. The value given as the dwc:cultivarEpithet should exclude any quotes. The term dwc:taxonRank should be used to indicate which type of cultivated plant name (e.g. cultivar, cultivar group, grex) is concerned. This epithet, including any enclosing apostrophes or suffix, should be provided in dwc:scientificName as well. |
| Examples | `King Edward` (for scientificName `Solanum tuberosum 'King Edward'` and taxonRank `cultivar`) `Mishmiense` (for scientificName `Rhododendron boothii Mishmiense Group` and taxonRank `cultivar group`) `Atlantis` (for scientificName `Paphiopedilum Atlantis grex` and taxonRank `grex`) |

nameAccordingTo
| Title (Label) | Name According To |
| Namespace | dwc |
| Table: | Identification Taxon |
| Description | A reference to the source in which a specific taxon concept circumscription is defined or implied - traditionally signified by the Latin "sensu" or "sec." (from secundum, meaning "according to"). For taxa that result from identifications, a reference to the keys, monographs, experts and other sources should be given. |
| Comments | This term provides context to the dwc:scientificName. Together with the dwc:scientificName, separated by sensu or sec., it forms the taxon concept label, which may be seen as having the same relationship to dwc:taxonConceptID as, for example, dwc:acceptedNameUsage has to dwc:acceptedNameUsageID. When not provided, in Taxon Core data sets the dwc:nameAccordingTo can be taken to be the data set. In this case the data set mostly provides sufficient context to infer the delimitation of the taxon and its relationship with other taxa. In Occurrence Core data sets, when not provided, dwc:nameAccordingTo can be an underlying taxonomy of the data set, e.g. Plants of the World Online (http://powo.science.kew.org/) for vascular plant records in iNaturalist (in which case it should be provided), or, which is the case for most dwc:PreservedSpecimen data sets, the dwc:Identification, in which case there is no further context. |

title
| Title (Label) | Title |
| Namespace | dcterms |
| Table: | Media |
| Description | A name given to a resource. |
| Comments | 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. 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"). |

| Table: | Media |
| Description | An account of the resource. |
| Comments | Description of collection or individual resource, containing the Who, What, When, Where and Why as free-form text. 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. |

CreateDate
| Title (Label) | Original Date and Time |
| Namespace | xmp |
| Table: | Media |
| Description | The date and time a 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. |
| Comments | 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. 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. |

| Comments | 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. 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.

| Description | The decimal fraction representing the frequency (rate) at which consecutive images (frames) were captured in real time for a dcmi:MovingImage, expressed as the number of frames per second. |
| Comments | This term represents the rate at which consecutive images were captured in real time, not the rate at which the media is encoded to play back the recording. For example, in a recording where 60 consecutive images (frames) are captured for each second of the real-time recording, this would be 60. In a time-lapse recording where one image (frame) is recorded every 5 seconds of recording, this would be 0.2. |

| Title (Label) | Resource Creation Technique |
| Namespace | ac |
| Table: | Media |
| Description | Information about technical aspects of the creation and digitization process of the resource. This includes modification steps ("retouching") after the initial resource capture. |
| Comments | 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. See also Subject Preparation Technique. Encoding method or settings, numbers of channels, lighting, frames per second, data rate, interlaced or progressive, multiflash lighting, remote control, automatic interval exposure. |

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, https://www.iso.org/standard/40874.html, but with year fields always comprising 4 digits. This makes datetime records compliant with 8601:2004. AC datetime values MAY also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus ("forward slash", '/'). dcterms:modified permits all modification dates to be recorded, or if only one is recorded, it is assumed to be the latest.

| Comments | URI from the ISO639-2 list of URIs for ISO 3-letter language codes, http://id.loc.gov/vocabulary/iso639-2. An image may contain language such as superimposed labels. If an image is of a natural scene or organism, without any language included, the resource is language-neutral with URI http://id.loc.gov/vocabulary/iso639-2/zxx corresponding to ISO ISO639-2 code "zxx". Resources with present but unknown language are to be coded as undetermined, with URI http://id.loc.gov/vocabulary/iso639-2/und corresponding to ISO639-2 code "und". Regional dialects or other special cases should conform to the ISO639-5 Alpha-3 Code for Language Families and Groups, http://id.loc.gov/vocabulary/iso639-5.html, where possible or the IETF Best Practices for Tags Identifying Languages, https://tools.ietf.org/html/rfc5646, where not.

| Comments | ISO639-1 two-letter codes are permitted but deprecated. 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. This is NOT dc: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. |

AC datetime values MAY also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus ("forward slash", '/'). 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.

| Table: | Media |
| Description | 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. |
| Comments | 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. 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).

The string SHOULD be a controlled value from the Audiovisual Core Controlled Vocabulary for Dublin Core dcterms:format, although it MAY be any Media Type (MIME type) value from the IANA list of Media Types (https://www.iana.org/assignments/media-types/media-types.xhtml) or any commonly used file extension string. Human-readable information about the Controlled Vocabulary for format is at http://rs.tdwg.org/ac/doc/format/. 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. |

In that case, the arc within an ac:Media resource plus the bounds of an ac:Media resource specify the region of interest. This term MUST NOT be used with ac:widthFrac or ac:heightFrac to define a region of interest. This term may be used with ac:xFrac and ac:yFrac to define a point. In that case, the implication is that the point falls on some object of interest within an ac:Media resource, but nothing more can be assumed about the bounds of that object. |

| Comments | Recommended best practice is to use a controlled vocabulary such as the Ontology of Units of Measure http://www.wurvoc.org/vocabularies/om-1.8/ of SI units, derived units, or other non-SI units accepted for use within the SI. For units that are composed of multiple parts, use the patterns as given in "A Primer for Communicating Mathematics via Plain Text" (https://cse.sc.edu/~fenner/latex-ASCII.pdf) by Stephen Fenner (e.g., `g/cm^3` for grams per cubic centimeter). For other units, provide the value as a recognizable standard (e.g., '%') or written out in full and in the plural (e.g., `individuals`). It is fine to provide non-SI units in the original language of the dataset. |

For other units, provide the value as a recognizable standard (e.g., '%') or written out in full and in the plural (e.g., `individuals`).

For units that are composed of multiple parts, use the patterns as given in "A Primer for Communicating Mathematics via Plain Text" (https://cse.sc.edu/~fenner/latex-ASCII.pdf) by Stephen Fenner (e.g., `g/cm^3` for grams per cubic centimeter). For other units, provide the value as a recognizable standard (e.g., '%') or written out in full and in the plural (e.g., `individuals`). It is fine to provide non-SI units in the original language of the dataset. |

For units that are composed of multiple parts, use the patterns as given in "A Primer for Communicating Mathematics via Plain Text" (https://cse.sc.edu/~fenner/latex-ASCII.pdf) by Stephen Fenner (e.g., `g/cm^3` for grams per cubic centimeter). For other units, provide the value as a recognizable standard (e.g., '%') or written out in full and in the plural (e.g., `individuals`). It is fine to provide non-SI units in the original language of the dataset. |

Visual Summary
The diagram below shows an overview of the DwC-DP tables (boxes) and the relationships between them (arrows). To avoid clutter, the diagram simplifies the representation of the model in a variety of ways. First, myriad join tables (tables that connect two classes in many-to-many relationships, e.g., EventMedia, MaterialMedia, OccurrenceMedia, etc.) are represented with stacks of boxes by category (e.g., under the box labeled ...Media) rather than with separate boxes for each join table. The relationships to the tables connected through the join tables are represented by single arrows (e.g., to the Media table) and the label "join to" rather than the myriad arrows that would otherwise be required. Second, the directionality of the relationships are shown with arrows, but the fields that connect the tables (keys), the cardinality of those connections (uniqueness and whether they are required), and the nature of the relationships (predicates) are not shown. The keys, cardinality and predicates are all shown in the sections for each table titled "Relationships to Other Tables".
Darwin Core Data Packages (DwC-DP) vs Darwin Core Archives (DwC-A)
Both Darwin Core Data Packages (DwC-DP) and Darwin Core Archives (DwC-A) are implementation schemas that use the Darwin Core Standard to share biodiversity-related data.
DwC-DP fully supports non-checklist datasets traditionally published as DwC-As (observations and physical specimens, with extensions), but it goes far beyond, allowing richer data to be shared from these traditional datasets than was hitherto supported. Also, it empowers those who desire to share entirely new types of data (biotic surveys with inferred absence and abundance, hierarchical material entities, organism interactions, and nucleotide analyses, among others) via Darwin Core.
