Future development MPDL

Software selection

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

	Magnolia	mediaWiki	eXist	eSciDoc
Webpage	​here	​here	​here	​here
MPIWG installation	see ​here	see this ​TRAC	see ​MPDL system	test system: see ​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	++	++	- 1	++
Stable	++	++	- 2	+
Performant	++	++	++	+
Customizable	++	++	++	++
Common use	++	++	+	-
In use at MPIWG	++	++	++	+
Easy administration	+	+	+	-
Free software	+	++	++	++

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

Extensions / Development

	Magnolia	mediaWiki	eXist	eSciDoc
Predefined extensions / templates	++	++ 1 2	-	-
Powerful programming	++ 3	++ 4	++ 5	+ 6
Easy application development	+	+	+	-

Notes / Annotations	-	-	-	-
Web page editor	++	++	-	-

Notes:
1: footnotes: ​internal, ​Cite
2: ​presentation of old books
3: Freemarker, Java Server Pages, XSL/CSS, limited XPath (works also in JCR 2.0 ?)
4: php, Java over JavaBridge?
5: Java, XQuery / XPath, XSL / CSS
6: Java
7: has to be implemented in Java (relative easy)

MPDL software

Get XML page fragment	-	-	++	-
Language technology	-	-	++	-
Document upload	++	++	- 1	+ 2
Web viewer	+ 2	+ 2	++	+ 2

Notes:
1: already implemented but not stable enough
2: has to be implemented (relative easy)
