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	​here	​TRAC	​MPDL system	​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

Basic

	Magnolia	mediaWiki	eXist	eSciDoc
Scalable	++	++	- [1]	++
Stable	++	++	- [2]	+
Performant	++	++	++	+
Customizable	++	++	++	++
Common use	++	++	+	-
In use at MPIWG	++	++	++	+
Easy administration	+	+	+	-
Free software	+	++	++	++

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

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)
8. at a point in the (XML)-document: after/before an element, after/before a word, at the 10th character after the beginning etc. (see XPointer)
