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

Functions which are not mandatory 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	+	++	++	++

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
