    Description: This document proposes a possible application profile that clarifies the use of the Dublin Core Metadata Element Set in libraries and library-related applications and projects. It was originally prepared by the DCMI-Libraries Application Profile drafting committee, a subset of the DCMI-Libraries Working Group. This revision was prepared in August 2004 and incorporates decisions made by the DCMI Usage Board at its meetings in 2003 and issues discussed in the WG meeting in Seattle in September 2003. It has been reformatted in conformance with the Dublin Core Application Profile Guidelines produced by the CEN MMI-DC Workshop.

    DC-Library Application Profile (DC-Lib)

    I. Introduction

    The concept of application profiles (see Application profiles: mixing and matching metadata schemas) has emerged within the Dublin Core Metadata Initiative as a way to declare which elements from which namespaces are used in a particular application or project. Application profiles are defined as schemas which consist of data elements drawn from one or more namespaces, combined together by implementors, and optimised for a particular local application.

    The DCMI-Libraries Working Group has explored various uses of the Dublin Core Metadata Element Set in library and related applications and has envisioned the following possible uses:

    • to serve as an interchange format between various systems using different metadata standards/formats
    • to use for harvesting metadata from data sources within and outside of the library domain
    • to support simple creation of library catalog records for resources within a variety of systems
    • to expose MARC data to other communities (through a conversion to DC)
    • to allow for acquiring resource discovery metadata from non-library creators using DC

    A library application profile will be a specification that defines the following:

    • required elements
    • permitted Dublin Core elements
    • permitted Dublin Core qualifiers
    • permitted schemes and values (e.g. use of a specific controlled vocabulary or encoding scheme)
    • library domain elements used from another namespace
    • additional elements/qualifiers from other application profiles that may be used (e.g. DC-Education: Audience)
    • refinement of standard definitions

    This document proposes a possible application profile that clarifies the use of the Dublin Core Metadata Element Set in libraries and library-related applications and projects. It was originally prepared by the DCMI-Libraries Application Profile drafting committee, a subset of the DCMI-Libraries WorkingGroup. This revision was prepared in August 2004 and incorporates decisions made by the DCMI Usage Board at its meetings in 2003 and issues discussed in the WG meeting in Seattle in September 2003. It has been reformatted in conformance with the Dublin Core Application Profile Guidelines produced by the CEN MMI-DC Workshop.

    2. Namespaces and Format of entries

    The DC-Library Application Profile uses terms from two namespaces:

    Format of entries:

    This Application Profile is presented following the " Dublin Core Application Profiles Guidelines" produced by the CEN MMI-DC Workshop.

    Name of Term A unique token assigned to the term
    Term URI A Uniform Resource Identifier used to identify the term.
    Label A human-readable label assigned to the term.
    Defined By An identifier of a namespace, pointer to a schema, or bibliographic reference for a document within which the term is defined.
    Source Definition The definition of the term in the namespace in which the term was orginated.
    DC-Lib Definition The DC-Lib definition of the term.
    Source Comments Comments on the term from the namespace in which the term orginated.
    DC-Lib Comments DC-Lib comments about the term.
    Type of term The grammatical category of the term (e.g. "Element", "Element Refinement", or "Encoding Scheme").
    Refines The described term semantically refines the referenced term. A refinement makes the meaning of the element narrower or more specific. It will share the meaning of the unrefined element but with a more restricted scope.
    Refined By The described term is semantically refined by the referenced term.
    Encoding Scheme For

    The described term, an encoding scheme, qualifies the referenced term. Using an encoding scheme will aid in the interpretation of an element value. These schemes include controlled vocabularies and formal notations or parsing rules. A value expressed using an encoding scheme will thus be a token selected from a controlled vocabulary (e.g., a term from a classification system or set of subject headings) or a string formatted in accordance with a formal notation (e.g., "2000-01-01" as the standard expression of a date). If an encoding scheme is not understood by a client or agent, the value may still be useful to a human reader.

    In some cases, encoding schemes not yet registered are indicated. These will be registered and/or approved by the DCMI Usage Board as DC Encoding Schemes in the future.

    Has Encoding Scheme The described term is qualified by the referenced encoding scheme.
    Obligation Indicates whether the element is required to always or sometimes be present. In this application profile the obligation can be: mandatory (M), mandatory if applicable (MA), strongly recommended (R) or optional (O). Mandatory ensures that some of the elements are always supported and mandatory if applicable means that this element must be supported if the information is available. An element with a mandatory obligation must have a value. The strongly recommended and the optional elements should be filled with a value if the information is appropriate to the given resource but if not, they may be omitted.
    Occurence Indicates any limit to the repeatability of the element.
    ## 3. Table of Contents [General](/specifications/dublin-core/library-application-profile/2002-09-24/#General) notes, open questions regarding all/some elements, ...

    Encoding Schemes:

    General notes regarding all elements:

    • Either a Title or Identifier are mandatory (Identifier is mandatory if applicable).
    • If the record is expressed in a format (e.g., HTML) that allows each element/qualifier/scheme value to be assigned a language attribute (e.g., the HTML tag lang="en"), the use of the attribute is permitted for any or all DC elements as desired.
    • All elements may be used as unqualified. If using qualified Dublin Core, additional guidelines are given.
    • Any encoding scheme that has a URI defined in a non-DCMI namespace may be used: DCMI will not define these. A mechanism to register these is awaited. Where applicable a table has been created for each encoding scheme in a separate section following the main body of tables for elements and refinements.

    Name of Term title
    Term URI http://purl.org/dc/elements/1.1/title
    Label Title
    Defined By http://dublincore.org/specifications/dublin-core/dcmi-terms/
    Source Definition A name given to the resource
    DC-Lib Definition -
    Source Comments

    Typically, a title will be a name by which the resource is formally known.

    DC-Lib Comments A parallel/transliterated title is considered a main title, i.e. the Title element is repeated.

    Either a title or identifier is mandatory. If no title is available, best practice is to give a constructed title, derive a title from the resource or supply [no title]. If using qualified Dublin Core, an element refinement for titles other than the main title(s) should be included.

    Retain initial articles and use local sorting algorithms based on language. A language qualifier may be used to indicate language of title if appropriate. (For example, see: Initial Definite and Indefinite Articles for a list of articles in various languages).

    This qualifier can include Title abbreviations as well as translations.

    DC-Lib Comments

    Assigned title such as uniform or key title is Alternative.

    Best practice is to use this element refinement for titles other than the main title.

    Retain initial articles and use local sorting algorithms based on language. A language qualifier may be used to indicate language of title if appropriate. (For example, see: Initial Definite and Indefinite Articles for a list of articles in various languages)

    DC-Lib Definition An entity with a primary role in the creation of the intellectual or artistic content of the resource.
    Source Comments

    Examples of a Creator include a person, an organisation, or a service. Typically, the name of a Creator should be used to indicate the entity.

    DC-Lib Comments

    This term should not be refined with a role. A subset of terms taken from the Library of Congress list of Relators have been approved as role refinements for Contributor (http://www.loc.gov/marc/sourcecode/relator/relatorlist.html). URIs will be provided when available. The DCMI Usage Board has disapproved the idea of structured values to provide more information about the creator - it should be in a description for another resource.

    Creator and Contributor may be conflated with Creator being used as a refinement of Contributor.

    Source Definition An entity responsible for making the resource available.
    DC-Lib Definition  
    Source Comments Examples of a Publisher include a person, an organisation, or a service. Typically, the name of a Publisher should be used to indicate the entity.
    DC-Lib Comments

    A subset of terms taken from the Library of Congress list of Relators has been approved for use as role refinements of Publisher if applicable (http://www.loc.gov/marc/sourcecode/relator/relatorlist.html). URIs will be provided when available. The DCMI Usage Board has disapproved the idea of structured values to provide more information about the publisher - it should be in a description for another resource.

    Although some applications may wish to conflate Creator, Contributor and Publisher, DC-Lib maintains the distinction between Creator and Contributor (which may be conflated) and Publisher. If the elements are conflated and Publisher used as an element refinement for Contributor, the resulting element would be mapped to DC.Publisher.

    Defined By http://dublincore.org/specifications/dublin-core/dcmi-terms/
    Source Definition The topic of the content of the resource.
    DC-Lib Definition  
    Source Comments Typically, a Subject will be expressed as keywords, key phrases or classification codes that describe a topic of the resource. Recommended best practice is to select a value from a controlled vocabulary or formal classification scheme.
    DC-Lib Comments

    If a geographic or temporal aspect is recorded use the element Coverage. It may also be repeated in Subject if desired. If there is a subject string with elements in addition to a geographic, include the entire string in Subject with geographic element also in Coverage.

    It is highly recommended that either freetext or controlled vocabulary be supplied as element Subject in the metadata where appropriate and feasible. It is also recommended that a controlled vocabulary be used with encoding scheme specified. If no encoding scheme is specified, it is treated as keyword.

    If using qualified DC, always use the encoding scheme(s) for terms from a controlled vocabulary.

    These are encoding schemes currently defined by DCMI. As additional schemes are registered, they will be included.

    Additional encoding schemes will be registered for those used in the library domain based on the MARC list of subject and classification schemes. Including an identifier to link to a registry where all encoding schemes are defined (e.g. based on RSLP schema) needs to be explored.

    DC-Lib Definition  
    Source Comments Typically, date will be associated with the creation or availability of the resource. Recommended best practice for encoding the date value is defined in a profile of ISO 8601 [W3CDTF] and follows the YYYY-MM-DD format.
    DC-Lib Comments

    Recommend use of an element refinement for type of Date. Recommend that dates be encoded:
    1) using W3C-DTF (a profile of ISO 8601 structured with hyphens),
    2) using ISO 8601 (structured without hyphens), or
    3) supplied as free text that does not take the form of a string of numerals (with or without hyphens).
    The second option, ISO 8601 (without hyphens), is preferred.

    It is acceptable to use widely-recognised practice such as day-month-year where the day and year are represented with numerals and month with a name or standard abbreviation (e.g., "1 January 2002" or "1 Jan 2002"). Avoid the use of potentially ambiguous date representations such as DD/MM/YY or MM/DD/YY (e.g., "04/05/05")

    It may be desirable to establish a DC-Lib encoding scheme or profile of ISO 8601 to cover B.C.E. dates, questionable and approximate dates. A date working group has been established to progress these issues.

Example of formal identification systems include the Uniform Resource Identifier (URI) (including the Uniform Resource Locator (URL)), the Digital Object Identifier (DOI) and the International Standard Book Number (ISBN).
    DC-Lib Comments

    Standard identifier: Provide at least one standard identifier from a standard scheme (e.g., URL, ISBN, etc.) if one or more standard identifiers have been assigned to the resource and are known to the metadata agency.

    Unique-resource identifier: Provide applicable identifiers assigned to one-of-a-kind resources (such as accession numbers assigned to items in a museum collection) if one or more of this class of identifiers have been assigned to the resource and are known to the metadata agency. If the structure of the identifier (e.g., all numerals) is potentially ambiguous it is recommended that the associated agencies' name be included as part of the identifier element.

    Citation: Provide a citation if no standard identifier is assigned and a formal citation is a common means of identifying the resource being described (e.g., a journal article).

    Use the element Identifier on a more abstract level; identifier for local library holdings like call number could be put into the DC-Lib element Location.

    Relation without qualifier is optional; where it is qualified the recommendation for the qualifier should be followed.

    If using qualifiers, use the most specific one that is applicable.

    When no Identifier is available, a bibliographic description may be constructed. Future work will involve developing guidelines.

    Recommended use with qualifiers in certain situations:
    - When documents in hand are parts of "host documents" (e.g. journal, monographic series) and when there is no citation information in DC identifier.
    - When documents in hand are revisions or reformatted issues of earlier publications and information on these are readily available.

    Defined By http://purl.org/dc/terms/
    Definition Internet RFC 3066 'Tags for the Identification of Languages' specifies a primary subtag which is a two-letter code taken from ISO 639 part 1 or a three-letter code taken from ISO 639 part 2, followed optionally by a two-letter country code taken from ISO 3166. When a language in ISO 639 has both a two-letter and three-letter code, use the two-letter code; when it has only a three-letter code, use the three-letter code. This RFC replaces RFC 1766.
