organizational

1. The next meeting is moved from Wednesday October 15th at 22:00 to Tuesday October 14th 21:00. (Heikki may not attend, or not say much, depending how things are going for the Big Bang at Geonovum the next day).

2. A face-to-face meeting is planned in Amsterdam at October 31st from 10:00 to 17:00. Location: In De Waag, Nieuwmarkt, Amsterdam (see ​http://www.indewaag.nl/?English). Jeroen, Erik and Heikki confirmed to be there, Jose is looking at tickets.

3. Heikki proposes an additional meeting at October 30th. Nobody confirmed -- please either confirm or reject that one.

on the implementation

1. Choices have been made to use Spring for IoC, Spring DAO using Hibernate and Hibernate Search.

---

on the architecture

Some confusions have been exposed, partially cleared up, but not totally.

The existing drawing of the architecture was found to be incomplete and possibly inadequate. Heikki will make a new one coming Thursday.

Main points :

1. we shall use the current database for storing metadata. This is known as Repository ;

2. just as it is now we'll keep a Lucene index of said Repository ;

3. we'll use a single Search Engine to be used by both the old codebase (which we'll have to modify for this) and by the new ebXML codebase ;

4. the Registry is an entity that corresponds to (or comprises) what also was called ebXML Object Model (see the wiki on that one here: ​http://trac.osgeo.org/geonetwork/wiki/ebXMLObjectModel) ;

5. the Database in the current architecture drawing is not understood by any of the current project members ;

6. the new CSW operations (using ebXML documents) are in the new Interface layer

7. the packaging of the new & old codebase is still unclear .. separate web apps or not, how to integrate the new single search engine for both new and old code
