As part of the UK vision for supporting open discovery principles in relation to education materials, JISC has sponsored a number of projects to assist in discovering and enriching existing resources. "Tagger" is one such project which has delivered three things:

• A basic web service API based around ExifTool, suitable for 3rd party use to geo-tag/geo-code image, audio, and video metadata.

• A demo web client enabling user upload, metadata parsing (from resource) and metadata enrichment (map based geo-tagging/geo-coding);

• An Open metadata corpus of geo-tagged/geo-coded enriched records with a REST based query interface. Currently, this bootstrap corpus consists of approximately a quarter of a million creative commons licensed geotagged images mainly sourced from Geograph.

Tagger supports the open discovery metadata principles.
