3.1 - Ricgraph
A new preprint was written: Rik D.T. Janssen (2025). Utilizing Ricgraph to gain insights into research collaborations across institutions, at every organizational level. [preprint]. https://doi.org/10.2139/ssrn.5524439.
The software created for that article has been integrated in Ricgraph and Ricgraph Explorer, causing a number of changes. There are also a number of improvements.
Ricgraph general:
- Added a batch script to get the collaboration diagrams (the figures in the preprint mentioned above).
- The file ricgraph.ini now has new parameters related to the software for the preprint.
- From now on, you can only use organization abbreviations of max. length 3.
- Improvements to the Makefile.
- Many small improvements (including code rewrites).
Ricgraph:
- Modifications for the preprint mentioned above.
- Ricgraph now prints its version on module initialization.
- Modifications in the functions that read from and write to a file for json, dataframe, and text formats. Changed order of function parameters for write_json_to_file().
- Full rewrite of the code that caches nodes. You can now both use a local cache or Memcached. Read more what to use.
Ricgraph Explorer:
- Modifications for the preprint mentioned above.
- Added an example Apache config file, so you can use Apache with login/password authentication.
- Updated awstats config file.
Documentation:
- Added the preprint mentioned above.
- Added a presentation.
- Added How to install Ricgraph on Windows using Windows subsystem for Linux (WSL).
- Added the Ricgraph October 2025 newsletter.
- Added University of Applied Sciences, Utrecht, projects with students.
- Renamed file ricgraph_pubs_pres_news_use_ment.md to ricgraph_outreach.md.
Upgrading:
- Save your ricgraph.ini file. Remove all of your existing files and directories, then re-install Ricgraph. Create a new version of ricgraph.ini, based on your old version and the file ricgraph.ini-sample. If you use organization abbreviations that have more than 3 characters, change them to have 3 characters (at most).
- You will need to reharvest your sources.
