The following improvements have been made to Ricgraph.

Structural change:

  • Previously, Ricgraph used the Python module py2neo to connect with the graph database backend Neo4j. This module is end-of-life. Now, Ricgraph uses the Python module neo4j. This required many changes, including explicit Cypher calls in the code. This results in a faster Ricgraph, and it may be possible to use other graph database backends that use the same Python module (such as Memgraph or Avantgraph).

Ricgraph Explorer:

  • Added a function that finds with which (sub-)organizations a person collaborates.
  • Modifications to make Ricgraph Explorer run in a multi-user environment. This includes an Apache config file, and changes so that Ricgraph Explorer can be run as a Linux service, or using WSGI.

Ricgraph:

  • Cleanup and optimization of code.
  • Added a script to count the number of organizations that contributed to a category, so that you will be able to see which (sub-)organizations collaborate.
  • Modifications to make Ricgraph run in a multi-user environment.
  • A call to get_personroot_node() or get_all_personroot_nodes() now returns person-root nodes of any type of node.
  • Previously, if a new node had a FULL_NAME that was already in Ricgraph, the new node was joined with the node already present. It appears that in case you harvest multiple source systems, this may not be a good idea: a person named J. Doe from source system 1 may be someone else than person J. Doe from source system 2. Thus, this is not done any more, unless you set RICGRAPH_NODEADD_MODE to something else than 'strict'.
  • Modified initialization file by renaming a section, and adding and renaming graph database backend parameters.
  • Removed function get_edges().

Harvest scripts:

  • Added University Medical Center Utrecht to the list of nodes to rename in the batch harvest script batch_harvest.py.

Documentation:

  • Added the reference publication: Rik D.T. Janssen, Ricgraph: A Flexible and Extensible Graph to Explore Research in Context from Various Systems. January 2024. Submitted to SoftwareX. https://doi.org/10.2139/ssrn.4712466.
  • Added use cases as in the reference publication.
  • Added documentation for Ricgraph Explorer.
  • Added documentation how to run Ricgraph and Ricgraph Explorer in a multi-user environment. Please read Ricgraph as a server on Linux.
  • Added a Ricgraph presentation and a table where Ricgraph has been used.
  • Added an explation how to dump data in Neo4j Desktop and use it in Neo4j Community Edition.
  • Reorganized the documentation structure.
  • Updated badges in README.md file.
  • And many other improvements and clarifications to the documentation.

GitHub:

  • The default branch name of Ricgraph in GitHub has been renamed from master to main.
