Summary

This project addresses a number of key problem areas identified by the Resource Discovery Taskforce and the Discovery programme, specifically: services that support the creation and enhancement of metadata, enhancements to existing aggregations, and services that support more effective reuse of metadata. The three strands of activities are:

GeoT

This project, funded under the auspices of the JISC 13/11 Discovery work programme, forms one work strand in wider EDINA efforts to address a number of the key problem areas identified by the Resource Discovery Taskforce and the Discovery programme, specifically: services that support the creation and enhancement of metadata, enhancements to existing aggregations, and services that support more effective reuse of metadata. This activity, 'GeoT' , concentrates on the development of a web service, based on open source software, to extract metadata from and embed new metadata in multimedia content, with a particular focus on geo- tagging of resources.

GeoT will wrap existing open source software for reading, writing, and manipulating image, audio, and video metadata, into a web service. The mature open source metadata manipulation tool, ExifTool, will provide the core capabilities for providing a generic web client that will allow users to upload multimedia files. These files will then be mined for their intrinsic metadata content and that content exposed for editing, enhancement and export. Whilst focusing on the geo-tagging (adding external tags outside a photo to provide location information) and geo-coding (embedding geographic location information within a resource e.g. in the EXIF metadata) metadata components, the tool will also provide a wealth of additional metadata about the uploaded resource which can in itself be used for richer discovery purposes e.g. camera make/model information, encoding, compression info (which can be important in determining if specific software can handle the resource).

EDINA fully supports the Resource Discovery Taskforce vision, being already a signatory to the Discovery Open Metadata Principles, and having contributed to phase 1 of the Discovery programme through release of OpenURL activity data (and provided an example of how the data might be used), and the GOLD project.

GeoT deliverables

JISC MediaHub

This activity will develop a crowd sourcing feature for use within JISC MediaHub which provides search result for video, image and audio resources from many collections. This will store metadata contributed by users, then make it searchable and available openly as part of the existing metadata aggregation. This improved metadata will also be fed back to the owners of the collection content.

JISC MediaHub deliverables

  • Extension of JISC MediaHub interface to support input of metadata by users
  • A framework to support storage, searching and re-supply to collection owners of metadata contributed by users
  • An open, user contributed, metadata corpus made openly available to machines alongside the existing mechanisms providing m2m access to the original JISC MediaHub metadata (OAI-PMH/SRU)
  • A summary of how the framework might be applied to other services

SUNCAT

This activity will enhance the SUNCAT service which provides information of the journal holdings of 80 HE and specialist libraries. It will take forward some of the recommendations identified by the Phase 1 project (SUNCAT Exploring Linked Metadata) which investigated how SUNCAT could make this data openly available as linked data.

SUNCAT deliverables

  • Increased corpus of metadata from the SUNCAT service made openly available, including different subsets that satisfy the individual requirements of a contributing library and take account of any copyright restrictions
  • Learning from other organisations/services working in this area
