We need to update the draft spec of the technical data model for Wiktionary support in Wikidata:

Uses:

• Designer: should be able to design interface and widgets to edit the data model. Designer needs to understand the model so they can decide what should/can be exposed to the user and which parts of the data model may be hidden and could be only implicitely in the UI.
• Community Manager: Needs to understand the model to answer the community’s questions. Needs the model to communicate it to the community.
• (new) Developer: Shared vocabulary, be able to consider the model in technical decisions
