Hi Joel, To add to both Vincent's and Dennis' posts, I wanted to let you know that the v4 resource models (formerly known as graphs) that are currently available (via the link that Vincent provided) are not exact copies of the v3 graphs because we tried to improve on both the organization and semantics based on our experiences thus far. Having said that, the new v4 graphs should accommodate the same data that the v3 graphs did. I will say that the Arches Designer makes it relatively easy to reevaluate your needs and make changes to the resource models before you load your data, but as Dennis noted, it will enforce semantic rules based on the CIDOC CRM, so do post any CRM related questions you might have as you go through this process.
Thanks!
