Version management of data #195

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It would be really useful to time stamp data with the creation data and the
last modified date.

The modified time stamps should allow the data to be versioned.

Perhaps Dublin Core has something for this.

I have proposed a simal:collected attribute to the schema so that we can track 
when a
fact has been collected. This allows us to take a different approach to version 
control.

Basically we keep all facts and the date they were collected (along with their
source) we can assume the most recently collected data is the most accurate.

See [Schema] for more details

The work on ISSUE 201 has changed the way data is stored. We now maintain a 
reference
to the original source of the information. This reduces the necessity for the 
data to
be versioned. I'm therefore marking this issue as won't fix until a more 
complete use
case emerges.

This issue is recently discussed on the list [1] and there it is agreed that 
it's 
usefoul to have the simal:collected timestamp.
I'm reopening this issue, because it hasn't been implemented yet.
