+## Protocol
+
+# OIHDataRecord
+- It likely that an additional "warpper" is needed e.g. "oihmessage"
+- oihmessage would include the oihdatarecord and an oihheader 
+- oihheader would include additional information such as a transactionId, a request time and possibly a "tenantID" (wording is not fix yet and needs to be revised)
+
+# Conventions
+- Do we allow elements & attributes? Discussion postponed to next meeting. Idea derived from XML.
+
+--> No differentiation between elements and attributes in JSON schemas/objects. Therefore no need to decide on this question.
+
+## Versioning
+- Postponed
+
+## Next Steps
+- [ ] Create graphical overview of oihmessage and oihheader
