SeedDMS
=======

Overview
--------

SeedDMS is a free document management system with web based user interface. It is based on PHP and PostgreSQL and uses built-in *Lucene* indexing engine for fulltext search.

Upstream URL: https://sourceforge.net/projects/seeddms/

Previewers and converters
-------------------------

SeedDMS uses LibreOffice components to generate thumbnails and PDFs of the imported documents. This is also useful for extraction of text for fulltext search. The main entry point is a third-party wrapper script called *unoconv* available from https://github.com/unoconv/unoconv/. This script wraps conversion functions of LibreOffice components, allowing to create a PDF out of virtually any ODF or OOXML document.

For previewers, additional chaining with *GhostScript* and *ImageMagick* is done in order to generate a thumbnail of the document. All conversions are entered as custom-defined commands in ``settings.xml`` SeedDMS configuration file.
