Building a Disciplinary Metadata Standards Directory

Building a Disciplinary Metadata Standards Directory

The Research Data Alliance (RDA) Metadata Standards Directory Working Group (MSDWG) is building a directory of descriptive, discipline-specific metadata standards. The purpose of the directory is to promote the discovery, access and use of such standards, thereby improving the state of research data interoperability and reducing duplicative standards development work. This work builds upon the ...

Cross-Disciplinary Integration of Metadata Descriptions

Within the ECHO (European Cultural Heritage Online) project an integrated domain of metadata repositories was created covering data from 5 different humanities disciplines. The integration required intensive work on encoding, syntactical and especially the semantic level, since interoperability is still difficult to be achieved. An ontology was created and a search engine that makes use of the ...

Metadata Standards for Educational Resources

E ach semester, I create Web-based learning experiences for my students by weaving together digital educational resources or learning objects such as videos, images, assessments, simulations, or tutorials. Often I use previously created material, if only I can find it. One current challenge of distributed learning is creating and managing content to facilitate reuse. Instructors as well as stud...

Directory-Based Metadata Optimizations for Small Files in PVFS

Modern file systems maintain extensive metadata about stored files. While this usually is useful, there are situations when the additional overhead of such a design becomes a problem in terms of performance. This is especially true for parallel and cluster file systems, because due to their design every metadata operation is even more expensive. In this paper several changes made to the paralle...
