BibTeX bibliographies can be imported, and selected references can be exported to BibTeX, Ris, and DocBook format.
refbase is a Web-based bibliographic manager that can import and export references in various formats (including BibTeX, Endnote, ISI, RIS, PubMed, MODS XML, OpenOffice, and Word 2007 XML).

Its OpenSearch and SRU/W services and support for unAPI and COinS metadata allow for easy access by clients and search engines.
bibtex2html is a collection of tools for translating BibTeX bibliographies to HTML. It can handle any BibTeX style (even those producing multiple bibliographies), use additional fields (like "abstract", "url", and "ps") to insert Web links, replace cross-references with links, sort on various fields, process simple (La)TeX macros, identify syntax errors in BibTeX files, and filter BibTeX entries based on a given criterion.
SiSU (Structured information, Serialized Units) is a lightweight markup based, text structuring and publishing framework (that features granular search). With minimal markup of a plaintext file, it produces: plain-text, HTML, XHTML, XML, ODF, LaTeX, PDF, and populates an SQL database at an object/paragraph level for granular searches. Prepare documents using your text editor of choice, then use SiSU to generate the desired output formats. SiSU is controlled from the command line.
