Lessons Learned from Building a Config-Based Knowledge Graph

We have been working with Knowledge Graphs for about a year and half now to solve some of the data needs at our company, and wrote up on some of the lessons we have learned in this process to share with the community. https://medium.com/vouch-engineering/building-a-config-based-knowledge-graph-e073834f852a

Snowflake is really well optimized for analytical queries that from our experience are really non-performative in Neptune

I don't but that definitely sounds intriguing. Our process generally involves taking data in snowflake and dumping into Neptune

if you do something like

for row in results:
   dict_results = row.asdict()

the dict_results will be in rdflib variables so like URIRef, Literal, etc so you may need to iterate through the dict and do .toPython() but it might be worth trying and seeing what happens if you write that dict_results to a csv. I haven't tried myself

my general practice to count the number of results from like a SPARQL query is to use

res = graph.query(sparql_query)
len(res)

Enforcing Unique Triples in RDF for sdo:Corporation Instances

If I want to enforce rules in RDF like this class can only have 1 triple with a certain predicate. For example, a URI that is rdf:type of sdo:Corporation can only have 1 name. I remember reading that is possible but can’t seem to find how to enforce that.
