Metadata Management and Semantics in Microarray Repositories

The number of microarray and other high-throughput experiments on primary repositories keeps increasing as do the size and complexity of the results in response to biomedical investigations. Initiatives have been started on standardization of content, object model, exchange format and ontology. However, there are backlogs and inability to exchange data between microarray repositories, which ind...

Data-driven Building Metadata Inference

Building Educational Metadata Application Profiles

Metadata schemas relevant to online education and training have recently achieved the milestone of formal standardization. Efforts are currently underway to bring these abstract models and theoretical constructs to concrete realization in the context of communities of practice. One of the primary challenges faced by these efforts has been to balance or reconcile local requirements with those pr...

Mapping Audiovisual Metadata Formats Using Formal Semantics

Audiovisual archives hold enormous amounts of valuable content. However, many of these archives are difficult to access, as their holdings are documented using a range of different metadata formats. Being able to exchange metadata is the key to ensuring access to these collections and to establish interoperability among audiovisual collections, between audiovisual collections and other cultural...

Emergent Semantics: Towards Self-Organizing Scientific Metadata

Tasked with designing a metadata management system for a large scientific data repository, we find that the customary database application development procedure exhibits several disadvantages in this environment. Data cannot be accessed until the system is fully designed and implemented, specialized data modeling skills are required to design an appropriate schema, and once designed, such schem...
