Current Situation
A resource belongs to a single package. A resource can only hold very limited pieces of information i.e a url, hash, a description and its format/type. It also has state i.e whether it is active and not active. They are versioned but not dated.
The user is given an option to reorder the resources against a package, this order has no relevance apart from how the information is displayed.
Use Cases
- Data should be able to be grouped by various different factors (type, date).
- There needs to be a mechanism to timeline data, so that search results only display the latest package. This needs to be done in a way that the older data is still easily accessible. This should be done with the minimum of user effort.
- The ordering of the data should be presented without the need for user input.
- There needs to more information stored against the data, beyond just its format and a description.
- Users should be able to refashion the data and post a whole new set of this refashioned data.
- Groups of data should be able to be synced across packages/instances.
- When new versions of the data arrive it should be easy to copy an old one and change versions/dates as required.
- A user may want to upload a resource separately from the package and decide later on where its the best place for it is.
Possible solutions
1 Make the data model for resources richer. The suggested model would be
Package <m2m> data_group <o2m> data <o2m> resource
data_group now becomes a first class entity.
The data group would be a holder for a timeseries of "data"
Each bit of data can have many resources of different types.
- Improve package relationships. This will involve giving package relationships more informations such as the date of the relationship in order to make a time series. (this date information could also be against the package)
- Add a package group table. All current packages get a package_group and then we will have a way to add packages in a time-line. Packages will have time series data information.
