== Software selection ==

We limit the software selection to the four systems Magnolia, mediaWiki, eXist and eSciDoc:

|| ||Magnolia||mediaWiki||eXist||eSciDoc||
||Webpage||  [http://www.magnolia-cms.com/ here]  ||  [http://www.mediawiki.org/wiki/MediaWiki here]  ||  [http://exist.sourceforge.net/ here]  ||  [https://www.escidoc.org/ here]  ||
||MPIWG installation||  see [http://hartmutkern.mpiwg-berlin.mpg.de/ here]  ||  see this [https://it-dev.mpiwg-berlin.mpg.de/tracs/mpdl-project-content TRAC]  ||  see [http://mpdl-proto.mpiwg-berlin.mpg.de/mpdl/query.xql MPDL system]  ||  test system: see [http://pubman.mpiwg-berlin.mpg.de/pubman/ Pubman]  ||

We examine the different software systems by means of their main functions and features for our extended user requirements in the area of web based access to XML-documents. The main new requirements are:
* state of the art web GUI
* datastore / repository functionality (user management, versioning of documents, history function)
* user notes / annotations within documents
* easy document uploads
* scalability

Functions which are not mandadory for our requirements are marked italic.

=== Basic needs ===

|| ||Magnolia||mediaWiki||eXist||eSciDoc||
||Scalable||  ++  ||  ++  ||  - ^[#note1 1]^ ||  ++  ||

||Easy administration||  +  ||  +  ||  +  ||  -  ||
||Free software||  +  ||  ++  ||  ++  ||  ++  ||

[=#note1 1]: not really scalable for many documents (> 1000 XML documents) [[br]]
[=#note2 2]: many system crashes at startup time (up to 2 days); sometimes system crash when a document is uploaded [[br]]

=== Datastore ===

[=#note2 2]: [http://wikisource.org presentation of old books] [[br]]
[=#note3 3]: Freemarker, Java Server Pages, XSL/CSS, limited XPath (works also in JCR 2.0 ?)[[br]]
[=#note4 4]: php, Java over JavaBridge [[br]]
[=#note5 5]: Java, XQuery / XPath, XSL / CSS [[br]]
[=#note6 6]: Java [[br]]
[=#note7 7]: has to be implemented in Java (relative easy) [[br]]
