Critical issues & discussion on pre-release 1.0

 * first input on pre-release 1.0(MPDL, evtl.)
 * v1.0 beta 4 has been delivered 16-09-2008

Outcome

Discussion on release 1.0

 * Feedback for Filter/Lists (MPDL, evtl)

Outcome
 * Natasa will give final feed back by next week
 * Update from 19.09. - First results sent to Matthias, Andre and can be discussed on the next VidCO.--Natasa 07:41, 19 September 2008 (UTC)


 * ticket 623 can not be delivered for release 1.0
 * other issues must be resolved, more time needed, info will be sent from Matthias

Institutional Visibility

 * new feedback provided on the Institutional visibility requirements discussion page
 * discussion on next steps
 * first functional sketch for retrieval (read access only, not yet dealing with updates) of components is on eSciDoc Access Rights . We created separate page not to work only with Institutional visibility. --Natasa 13:16, 22 September 2008 (UTC)

Outcome --Natasa 09:49, 30 September 2008 (UTC)
 * A Range of IP addresses will be considered as separate user handle. It will be on the side of the solution to identify the Ip address from the user request and associate correct user handle with it.
 * Michael and Natasa will talk further on this issue
 * Update: first concepts exchanged tbd on next conference, see ESciDoc Developer Workshop 2008-09-30

TOC

 * feedback and status
 * structural relations between Toc and Container - are different from member and container?

Outcome
 * There are TOC methods in developer build and not in the pre-release
 * there has been discussion between Natasa and Frank (regarding the structural relation between Toc and container)
 * FIZ will provide proposal and time-scale

Containers and members

 * Not discussed

Miscelaneous

 * The Role of XACML policies
 * XACML in its origin is used by the PDP almost by all handlers when working with single object
 * XACML is translated into the query when working with current filter solutions and with lists of objects
 * Matthias provided input that many other systems do not have such complex authorization rules and do not implement them
 * Both FIZ/MPDL agreed that after release 1.0 we should work on an API for defining XACML policies, as XACML policy in its original form is hard to be created, is not intuitive and may lead to unexpected behaviour.


 * Filters and item lists
 * FIZ provided an information that there is still a dilemma whether to use Relational database for the fast item lists retrieval or to use Lucene (considered for enable administrative searches and filtering as well). Both tracks are started and tested and FIZ needs more time to make proper decision. In case when Lucene is used, again XACML policies would have to be converted. FIZ tests are mostly oriented towards performance and scalability.
