Stewardship of LRMI specification transferred to DCMI

2014-10-24, After lengthy deliberations, the leadership of the Learning Resource Metadata Initiative (LRMI) has determined that the stewardship of the LRMI 1.1 specification, as well management of future LRMI development, will be passed to DCMI and its long-standing Education Community. The LRMI specification on which schema.org educational properties and classes are based was created by the Association of Educational Publishers (AEP) and Creative Commons (CC) with support from the Bill & Melinda Gates Foundation. The three-phased development cycle of the LRMI 1.1 specification included closing processes for the orderly passing of stewardship to a recognized organization in the metadata sector with commitments to transparency and community involvement. Stewardship of the LRMI specification within DCMI will be a function of a DCMI/LRMI Task Group. The LRMI specification as well as links to the Task Group and community communications channels can be found on the DCMI website at http://dublincore.org/dcx/lrmi-terms/. For the full announcement of the transfer, see the AEP press release at http://www.lrmi.net/lrmi-transfers-stewardship.

Tutorials, presentations and proceedings of DC-2014 published

2014-10-24, Over 236 people from 17 countries attended DC-2014 in Austin, Texas from 8 through 11 October 2014. Pre- and post-Conference tutorials and workshops were presented in the AT&T Executive Education and Conference Center and at the Harry Ransom Center with 90 people attending in each of the two venues on the University of Texas at Austin campus. Over 190 people attended the 2-day conference. Presentation slides of the keynote by Eric Miller of Zepheira LLC as well as presentations from the special sessions and the tutorials/workshops are available online at the conference website at http://bit.ly/dc2014-presentations. The full text of the peer reviewed papers, project reports, extended poster abstracts and poster images are also available. Additional assets from the conference will be added to the online proceedings as they become available over the next few weeks.

DCMI/ASIS&T Webinar - The Learning Resource Metadata Initiative, describing learning resources with schema.org, and more?

2014-10-24, The Learning Resource Metadata Initiative (LRMI) is a collaborative initiative that aims to make it easier for teachers and learners to find educational materials through major search engines and specialized resource discovery services. The approach taken by LRMI is to extend the schema.org ontology so that educationally significant characteristics and relationships can be expressed. In this webinar, Phil Barker and Lorna M. Campbell of Cetis will introduce schema.org and present the background to LRMI, its aims and objectives, and who is involved in achieving them. The webinar will outline the technical aspects of the LRMI specification, describe some example implementations and demonstrate how the discoverability of learning resources may be enhanced. Phil and Lorna will present the latest developments in LRMI implementation, drawing on an analysis of its use by a range of open educational resource repositories and aggregators, and will report on the potential of LRMI to enhance education search and discovery services. Whereas the development of LRMI has been inspired by schema.org, the webinar will also include discussion of whether LRMI has applications beyond those of schema.org. Registration at http://bit.ly/dcmiWebinar-LRMI. The webinar is free to DCMI Individual & Organizational Members, to ASIS&T Members, and at modest fee to non-members.

DCMI's first Governing Board officer transition

2014-10-24, In the closing ceremony of DC-2014, DCMI exercised the first Governing Board officer transition under the Initiative's new governance structure. Michael Crandall stepped into the role of Immediate Past Chair as Eric Childress assumed the roles of Chair of DCMI and the Governing Board. Joseph Tennis became the new Chair Elect of the Board and will succeed as Chair at DC-2015 in São Paulo, Brazil. Information about the new DCMI governance structure can be found in the DCMI Handbook at http://wiki.dublincore.org/index.php/DCMI_Handbook/orgStructure

DCMI logo 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.

DCMI logo Current DCMI Work Themes

DCMI has a set of "work themes" that focus the Initiative as a whole and change as the metadata ecosystem 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.
