Dear Amanda, thank you for your interest in the methods.
As I guess you know well, heterogeneous (especially civic society networks) are super complex as entities are often variably formalized, resourced, often 'unstable' and sometimes resist normalization and classification.
To illustrate in our work, some start as 2-3 people, then informal groups, become initiatives or coordinations of entities, later maybe NGOs, that create projects that are often more visible than themselves and might work outside of one entity, even becoming a new one (spinning-off). This creates fairly dynamic, vibrant and contemporary cultural outputs and effects, but it is hard to capture and process.
CLUBTURE.org network is particularly good in supporting (even under-resourced) in open and participatory grass-root culture, then advocating for its support in doing events, research, publications...but also people do drop out, projects fail and what not. There could be a better capture of all to reflect and learn. For start we entered 50+ organizations, 10+ key infrastructure entities (and their DKC-HR network) in Wikidata and some basic info on Wikipedia and media on Commons, just to have initial minimal visibility and clarity. Mind you I still need to make the first Wikidata:Property proposal and figure out what is most useful. We have indeed already started exploring how to visualize networks across different types of spatial maps, timelines, but also want to think about capacities (on scale fully volunteer hobist to fully professional NGO), types and levels of activities (local - int. but also topical vs. interdisciplinary) and visibility (use of soc. media and institutional recognition)... with a huge challenge of this not being just single points of (static) views.
Actually I hope that this can be useful for others in Wikimedia to track and learn about dynamics of diverse entities (for example of Wikimedia Affiliates), which are hugely different and hard to grasp as 'network', unless you are fully committed insider with not only access to info, but capacity to make it useful insight and knowledge.
If you think we could work together and engage others with more general discussion on methods of tracking networks on Wikidata we can maybe start with a zoom session and maybe create WikiProject for it? https://www.wikidata.org/wiki/Wikidata:WikiProject_Networks_of_organizations ?
Best - Z.
