One record per dependency is indeed the case at the RDBMS level, but there's no reason why that scheme needs to be slavishly copied over to the JSON. Let me try to illustrate this. I couldn't find any modelling code in Donald's public repo - I checked both branches and couldn't find it (Donald, please point me to it if it's on GitHub rather than just your local clone). So I knocked up a simple model (using SQLAlchemy, but the model is so simple that just about any ORM should do). The entities are Project, Release and Dependency. I've created a simple script, depmodel.py, along with two JSON files which have the relevant subset of the PEP 426 metadata for setuptools 0.7.7 and Pyramid 1.4.2. These are available at https://gist.github.com/vsajip/5929707 This code/data uses the older schema (run_requires / run_may_require, etc. and using 'dependencies' rather than 'install' as a key). This is the JSON which is supposed to be problematic, so I wanted to see what the problems might be. I couldn't find any, so I'm linking to the code here so that Donald/Nick can point out any misunderstanding on my part. The script allows importing the dependencies from JSON to RDBMS (34 lines for the import function) and also exporting from RDBMS to JSON (43 lines for the export function). I've used SQLite for the database. python depmodel.py -i setuptools-0.7.7.json will read the dependencies into SQLite, and python depmodel.py -e setuptools/0.7.7 will print the SQLite records as JSON. I understand that people might have particular preferences, but I can't see any technical reason why we couldn't have lists in the JSON. The import and export code looks pretty simple to me. What have I missed? Regards, Vinay Sajip _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
