I need a document converter software that provides a simple webservice api. The software receives conversion jobs through the api and does the conversion to the selected output format using OpenOffice/LibreOffice.
* A job consists of a input file (DOC, DOCX, PPT, XLS, PPTX, PDF etc.) and output format settings (format like PNG, SVG, JPG, PDF and corresponding quality settings, etc.). Output settings and input file (file upload or path to file) are post params. All settings/params that can be seen in File > Export dialog should be supported.
* The api answers in JSON format: status ok/not ok and path to output file(s)
The software shall be based on OpenOffice/LibreOffice UNO api, so C++/Python/Java programming languages can be used. The software is for internal use only, so no authentication, acl's, etc. required.
The software must be able to process several concurrent jobs. therefore a pool of OpenOffice instances must be maintained.
There is already a library/tool "jodconverter" (see http://code.google.com/p/jodconverter/) that could be used as basis.
