Records, Documents, & Graphs (II)

On the need for running code and rough consensus.

If you want to make the Semantic Web a reality, stop making the case for it and spend your time doing something more useful, like actually making machines smarter or helping people publish data in a way that’s useful to them. Manu Sporny, "JSON-LD and Why I Hate the Semantic Web" --21 Jan 2014

Context

This document is an attempt to bring together several parallel discussions that revolve around the lack of a shared understanding on how to represent RDF resources in relation to the (pre-existing) concepts of records, documents, objects, and graphs. In particular:

StepStool has a few convenience actions:

- ladder:init  will delete all existing data (including files) and re-initialize your account
- index:init  will delete the index but retain all mapped objects; it will NOT rebuild the index
- index:reindex  will rebuild the index in real-time (ie. will not delete it first)
- index:query  will query the index and return a response in JSON

Ladder will respond to several REST endpoints that aren't documented in StepStool.  These are:

GET /resources  - list all resources (paged using &page and &per_page)
