[db-wg] [ncc-announce] [news] Phase 1 of Deprecation of "changed:" Attribute Deployed to RIPE Database Release Candidate Environment

Dear Ewa, working group,

I understand there is some confusion about the actions required from users of the database for this.

We documented the impact on users of the database for each phase of the project here:
https://labs.ripe.net/Members/tim/deprecating-the-changed-attribute-in-the-ripe-database 

But let me summarise.

Phase 1: Introduce the new attributes “created:” and “last-modified:”

 (currently deployed to the Release Candidate environment)

 = w.r.t. updates / existing objects
 
 No action required, these attributes are added automatically by the database.

 = w.r.t. parsing objects

 If your scripts are RFC compliant they should ignore unknown attributes.
 But it's a good idea to make sure - using the release candidate environment.
 
 If you were relying on "changed:" you should start using "last-modified:" instead now.


Phase 2: Make the "changed:" attribute optional

 = w.r.t. updates

 You are strongly encouraged to stop including "changed:" in your updates.
 You can still include "changed:" in your updates, but you will receive warnings.

 = w.r.t. parsing objects

 Objects will start to appear that do not have "changed:" lines.
 If you were relying on "changed:" and did not update your scripts in phase 1,
 you should do so now.

Phase 3: Deprecate the "changed:" attribute

 = w.r.t. updates / existing objects

 "changed:" is removed from existing objects in bulk - this will be visible in history, but will not affect "last-modified:"
 Updates may no longer include "changed:". Doing so will result in errors.

 = w.r.t. parsing objects

 "changed:" will be removed from all objects
 If you were relying on "changed:" and did not update your script in phase 1 or 2,
 you should really do so now


I hope this helps. Please let us know if you have any questions or comments.

Kind regards,

We do not understand how we would add so many attributes "last-modified:" and "created:" to tens of thousands our records registered in ripe database? It takes a long time and  we are obliged to modify it to the end of July 2015.
