Work Items

---

To summarize the currently assigned work items per person:

Erik van Ingen

• Hibernate Search. Will probably be used, needs more research
• create DAO layer
• create Hibernate mapping for the DAOs

Heikki Doeleman

• model Basic Extension Package
• model ISO Extension Package
• decorate the above with JiBX

Jose Garcia

• CQL parser (refer also to ​GeoTools)
• support Filter Expressions (refer also to ​GeoTools)

---

This is the full list of work items:

Service Layer

• implement Java classes to handle CSW/ebRIM operations
  • Prio: 2
• expose these as Web Services using (probably) Axis2
  • Prio: 2
• decorate these with a SOAP/WSDL interface
  • Prio: 2

CSW/ebRIM model

• model the CSW/ebRIM operations' payload in Java
  • Prio: 2
• decorate these with JiBX
  • Prio: 2

Search Engine

• CQL parser (refer also to ​GeoTools)
  • Prio: 1
  • Jose Garcia
• XPATH support. How to implement this w.r.t. our DBMS / Lucene index is not immediately obvious and needs more research
  • Prio: 3
• Hibernate Search. Will probably be used, needs more research
  • Prio: 1
  • Erik van Ingen
• support Filter Expressions (refer also to ​GeoTools)
  • Prio: 1
  • Jose Garcia
• the search engine needs an interface so we can actually use it to search
  • Prio: 1

ebRIM / Registry / Information Model

• model Basic Extension Package
• model ISO Extension Package
• decorate the above with JiBX

Persistence Layer

• create DAO layer
• create Hibernate mapping for the DAOs
• implement Lucene index
• implement spatial query support (beyond Bounding Box)

Access Control

• read the specification and research how to do this

Miscellaneous

• integrate the new code with the legacy codebase
• ebRIM Updater: create a system that updates the new persistent storage everytime an update is done to the existing persistent storage
• finalize work related to Maven, Ant, and Installer <font color="blue">scripts</font>
• create a GeoNetwork Maven repository
• write documentation and tutorials
