Almost all of the data in this site passes through the Jena framework:

https://legalentityidentifier.info/lei/lookup/

Most of the data is in a TDB model,  although there is an embedded
Lucene index for search and navigation.

There is a write up about it at

http://ontology2.com/the-book/legalentityidentifier-info.html

That second page is also rendered by a Jena-based system.  In this case
there are a number of HTML source files that are combined with other
things to make the pages.  Metadata is extracted from the pages and
stored in an in-memory model,  then queried.

There is also a CRM system that processes web forms,  sends emails, 
etc. that runs in AWS with DynamoDB.  One cool thing there is that I
write business rules in the Jena Rules language to deal with how
messages get routed,  which messages are spam,  etc.
