Automatic Metadata Enrichment Plug-in for GeoNetwork Opensource
The research team has successfully developed four plug-ins to facilitate metadata automation in Geonetwork. This is part of Proof of Concept for Spatial Metadata Enrichment. These plug-ins include:
Suggestion list plug-in: this plug-in provides of a suggestion list based on previously searched terms. Using this Plug-in in Geonetwork, all subsequent searches benefit from previous searches. This facility provides a user-generated context for metadata creation and automation.
Tag Cloud plug-in: this plug-in provides a visual representation of user generated search words and tags’ relative importance in the Geonetwork’s user interface. The Cloud is enriched by user interactions on metadata records. Through this means a user-generated taxonomy can be established.
Tag monitor plug-in: this plug-in automatically observes users interaction with Geonetwork and collects users recognition of and feedback on metadata records. The plug-in monitors every interaction of users including downloading, exploring metadata details, etc. It also asks users to submit new keywords, agree or disagree with existing key words.
Process based data entry: this plug-in is a metadata data entry user interface that has been designed in accordance with metadata and data generation life cycle. Through this interface, the metadata entry process has been aligned with spatial data creation life cycle. All associated data elements in a certain spatial data creation step are grouped and linked together in separate steps of metadata entry.
