+= 'Hello fellow project members,' =
+
+here are the minutes of the last chat on the ESA project. Find it also on the wiki here: http://trac.osgeo.org/geonetwork/wiki/esa-10-10-2008.
+
+----
+
+== ''attending'' ==
+
+present: Jose, Heikki, Jeroen, Erik
+
+----
+
+== ''summary'' ==
+
+We discussed the general architectural layers in the new project, its relation to the current codebase, and next meetings.
+
+----
+
+== ''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 enity 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
+
+----
+
+== ''work items next week'' ==
+
+1. meeting at Tuesday 21:00 !
+
+2. Erik will start work coming Tuesday and work Tuesdays, Wednesdays (50%) and Thursdays from then on
+
+3. what will you be doing Tuesday Erik? Start setting up a Spring DAO layer that uses Hibernate ?
+
+4. Heikki will spend no time on ESA until Thursday, when he makes a new architecture diagram
+
+5. the work items for Jose and Jeroen were not specified during this meeting
+
+
+As usual, please comment on both the contents and form of these minutes.
+
+Kind regards
+Heikki
