The Dublin Core^® Metadata Initiative

The Dublin Core Metadata Initiative, or "DCMI", is an open organization supporting innovation in metadata design and best practices across the metadata ecology. DCMI's activities include work on architecture and modeling, discussions and collaborative work in DCMI Communities and DCMI Task Groups, global conferences, meetings and workshops, and educational efforts to promote widespread acceptance of metadata standards and best practices.

DCMI maintains a number of formal and informal liaisons and relationships with standards bodies and other metadata organizations.

DC-2013 in Lisbon on 2-6 September 2013 will explore questions regarding the persistence, maintenance, and preservation of metadata and descriptive vocabularies. The need for stable representations and descriptions spans all sectors including cultural heritage and scientific data, eGovernment, finance and commerce. Thus, the maintenance and management of metadata is essential to address the long term availability of information of legal, cultural and economic value. On the web, data—and especially descriptive vocabularies—can change or vanish from one moment to the next. Nonetheless, the web increasingly forms the ecosystem for our vocabularies and our data. DC-2013 will bring together in Lisbon the community of metadata scholars and practitioners to engage in the exchange of knowledge and best practices in developing a sustainable metadata ecosystem.

Announcements

DCMI-AsiaPac regional workshop in Singapore: "RDA, DC and Linked Data"

2013-05-29, DCMI-AsiaPac will hold a regional workshop in Singapore on 15 August 2013 as part of the DCMI Regional Meetings Series. The theme for the one-day workshop will be "RDA, DC and LOD" and will be comprised of two half-day seminars. The Workshop will be held the day before the IFLA IT Section's conference on "User interaction based on library linked data" on 16 August. IFLA WLIC itself will run from 17-23 Aug 2013. Through the Workshop, the organizers intend to raise the awareness among librarians in the Asian region on the implementation of RDA and how library metadata (specifically DC) can be exposed as linked data to improve visibility and enhance collection usage. The objective is also to build confidence among Asian librarians to work well in the digital arena and be comfortable enough to adopt new technologies that will help improve their libraries' services. A secondary objective is to build a community for the DCMI Asia Task Group where regular discussion on metadata matters can be established. More information about the workshop is available at http://dcevents.dublincore.org/BibData/ap2013.

UW iSchool joins DCMI as inaugural Institutional Member

2013-05-29, DCMI is please to announce that the Information School of the University of Washington in Seattle, USA, has joined DCMI as the inaugural Institutional Member in the Initiative's revised membership programs. As a leading member of the iSchool movement, the University of Washington Information School is a model for other information schools around the globe. Assistant Professor Joseph T. Tennis will represent the Information School on the DCMI Oversight Committee. Regional, Institutional and Supporting members of DCMI are pivotal to guaranteeing the continuing contributions of DCMI to the metadata community. Information about the revised membership programs is available at http://dublincore.org/about/membershipPrograms/.

DC-2013 Session: Long-term Preservation and Governance of RDF Vocabularies

2013-04-17, The DC-2013 Special Session titled Long-term Preservation and Governance of RDF Vocabularies will be sponsored by W3C and will focuses on issues related to the usability of RDF vocabularies in the long term (as defined in "decades") including continued access to documentation, inheritance of ownership and maintenance responsibility, and the continued resolvability of domain names. The usability of Linked Data relies on the ability to interpret what the data means, which depends on the availability of the RDF vocabularies used in the data. RDF vocabularies are created by a wide range of people and institutions, from individual researchers to national libraries and for-profit corporations, for a wide range of descriptive requirements. The oldest RDF vocabularies in existence are just fifteen years old. It is time to look systematically at how ownership and responsibility for today's vocabularies will pass to the next generation. For a fuller description, see http://dcevents.dublincore.org/IntConf/index/pages/view/vocPres. DC-2013 will be held in Lisbon 2-6 September 2013. The conference website can be found at http://purl.org/dcevents/dc-2013.

Current DCMI Work Themes

DCMI has a set of "work themes" that focus the Initiative as a whole and change as the metadata ecology evolves. The themes address broad issues in metadata that cut across the more siloed interests of domain-specific Communities and Task Groups within the Initiative. These DCMI-supported work themes receive targeted attention and commitment of resources from DCMI as an organization.

Platform-independent Application Profiles

The DCMI Abstract Model (DCAM), published as a DCMI Recommendation in 2007, provides an abstract syntax for packaging Semantic-Web-compatible data in validatable record formats. DCAM was designed to bridge the modern paradigm of the unbounded Linked Data graph and the more familiar paradigm of the validatable metadata record, locally managed and constrained using a myriad of software platforms and implementation technologies. For five years, DCAM has inspired a wide range of deployment experiences, and the core RDF standards themselves continue to be extended. The activity "platform-independent application profiles" is re-evaluating the need and requirements for a common language to express metadata design patterns, both as templates for Linked-Data-compatible data formats and as reference points for creating and consuming coherent metadata within communities of discourse and practice.

Mapping Diverse Vocabularies

While DCMI Metadata Terms and other core vocabularies increase the coherence of metadata by providing shared reference points, the unavoidable proliferation of diverse but overlapping vocabularies threatens to create metadata silos. A key part of the solution is to create machine-readable mappings. The activity "mapping diverse vocabularies" aims at mapping DCMI metadata terms to related terms in other vocabularies. In the absence of well-established practices for publishing and maintaining such mappings, this activity aspires to establish a workflow and publication practices that can be adopted by other vocabulary maintainers. The starting point for this activity is a mapping to the terms defined by the Schema.org initiative.

Sustainable Vocabularies

As a foundation for applications, the value of any given vocabulary depends on the perceived certainty that the vocabulary—both its machine-readable schemas and human-readable specification documents—will remain reliably accessible over time and that its URIs will not be sold, re-purposed, or simply forgotten. In order to raise awareness of this issue, DCMI has formulated an agreement with the FOAF Project, which is owned by individuals, with contingency plans for transferring maintenance control in the short or long term should exigent circumstances require. This activity examines the issues around vocabulary sustainability and governance with the goal of formulating best practices and, ultimately, of ensuring that our vocabularies will be preserved by society's long-term memory institutions.
