I have a model that lists my artifacts such as catalogs of applications, servers as well as diagrams that model the environment and matrices that show relationships. I am however unclear how these can be classified so that they align to TOGAF.
For example is the classification Artifacts > Catalog > Servers correct? What if there are human elements such as Actors and documentation as well as intangible concepts and principles such as LDAP, DNS, etc.
Is there a base template that has the appropriate package structure and classification that I can use in Sparx Enterprise Architect?
I think you can look into the view and view points concept in EA, here is an TOGAF v8 online doc , which shows Zachman model of various view and view points. Check the picture for Table: Mapping of Example Taxonomy of Architecture Views to Zachman Framework.
I believe for your case, the proper catalog could be System model - Network or Technology constrained model - Network views.
Also here is another TOGAF v9 doc, check 35.7 Recommended Architecture Views to be Developed, you could look into 35.7.3 Developing a Software Engineering View
