I have identified an organization which is willing to spend up to about EUR 10,000 on adding support for exporting MediaWiki pages as PDF files, and improving document management for documents consisting of multiple pages.
My current thinking is that the functionality implemented, as a minimum, would be as follows: a) Using an extension, integrate of a "PDF link" on any wiki page which would call an external library like HTMLDOC on a single wiki page b) Support filters on the rendered HTML (replacing image thumbnails with high resolution images, filter content by regular expression, etc.), and revision filters (export last revision edited by user on whitelist Y, or approximating currentdate-Z) c) Create a "PDF basket" UI which makes it possible to compile a PDF from multiple pages easily (and rearrange the pages in a hierarchy). The resulting structures could potentially also be stored as wikitext, using a new <structure> extension tag, so that they can be used both by individuals compiling PDFs for personal use, and by groups collaborating on complex documents.
Possibly some budget could also be allocated for improving the external PDF library used, especially if we can allocate additional funds for this project.
I'd like to request comments on this approach, specifically: - Besides HTMLDOC, do you know a good (X)HTML-to-PDF library which could be used for this purpose? - Within this budget, do you believe an alternative approach which utilizes an intermediate format is viable (e.g. wiki-to-Docbook-to-PDF), given the complexity of the MediaWiki syntax, its various extensions, and the need to keep up with parser changes? - If you are a developer, would you be interested in working on this project, and available to do so? (If so, please contact me privately.)
Any other comments would also be appreciated.
