 ## Approach
 
-* Get the *-ro-crate-metadata.json files (e.g. via git submodules?)

+
+* Get the *-ro-crate-metadata.json files, currently via git submodules (see 'collect_crates.py')
+
+* Validate the RO-Crates using a SHACL profile (see "gide_shapes.ttl" for the profile and "validate_crates.py" for processing)
+
+* Generate an "index.html" displaying the compliance stats for the crates
+
+TODOS: Add URI-level validation (are ontology entries correct/valid? which ontologies are used?)
+
+### 2 - Serialize and export
