A proposed reporting tool for DSpace based on the DSpace 4.x REST api.

• See the dialog related to this use case on the DSpace Wiki

This code illustrates a mechanism to filter DSpace items by use case and item properties.

The code allows a set of use case filters to be defined.

• Enum defining available filters to be applied to a collection of items

The purpose of this client code is to illustrate how quickly a useful client application could be built by extending the REST API to support the ability to filter collections.

• Sample Filter Client Page
• Sample Filter Client JS
• Sample Client Screen Shots

This tool allows a user to query for items based on the presence of one or more metadata fields within an item. The tool supports 8 operators: exists, doesn't exist, equals, not equals, like, not like, matches, doesn't match. More than one operation can be provided.

The purpose of this client code is to illustrate how quickly a useful client application could be built by extending the REST API to support the ability to query item metadata.

• Sample Query Tool Client Page
• Sample Query Tool Client JS
• Sample Query Tool Client Screen Shots

• Additional code needed in the DSpace REST API to support these capabilities

• /metadataregistry - Return the Metadata Registry
• /filters - Return a set of pre-defined filters for items of interest
• /filtered-collections - Return items / item counts within a collection that satisfy a filter
• /filtered-items - Return items that match a metadata query
