The last 3 years I have been involved in the Wf4Ever project, which has developed the notion of Research Objects and their respective models (previously introduced another post). Lately I have been exploring new ways for eating my own dog food by associating Research Objects to my papers as HTML web pages (see an example here). These Research Objects are useful, as they serve as summary for the paper in question, and they have pointers to all the datasets, queries and additional materials that I could not include in the paper.

However, I realized that I spent a lot of time creating them and annotating them. Therefore during last Christmas I have created a Research Object Creator tool, which takes as input a LaTeX file and extracts its title and abstract to create an annotated page in rdf-a. It also produces a structure of the contents to reference, so you only have to fill in (and annotate if you want) the resources to point to. A sample can be seen in the image below:

The tool is available in Github, so if you want to try it out with a LaTeX paper click on the following link:

Finally, I have also created a landing page for showing the current catalog of Research Objects: The page is generated automatically and given a URI of a Research Object, it extracts its title and abstract from the rdf-a descriptions. If you want to contribute with new URIs, modify the Constants file in the Github project ( and I will recreate the landing page. Note that for this project I have used the Semargl rdf-a parser (, which is a little bit strict when parsing the HTML pages. If your Research Object has any markup mistakes, the parser will fail.
