[Dev] Maintenance to CMDI infrastructure on 2016-07-07 and 2016-07-08

[Twan Goosen]

Dear all,

Next Thursday, 7 July, we will update CLARIN's metadata infrastructure, 
adding support for CMDI 1.2. As a result, the Component Registry and the 
VLO will be unavailable at times throughout the day while we carry out 
the required updates. We will add more detailed information with respect 
to the status and planning to the service monitor page on the CLARIN 
website[1] as it becomes available. There may be some additional 
downtime for these services on 8 July as well.

As stated before, these updates will *not* affect existing CMDI 
components, profiles and instances, and no immediate action from the 
centres will be required. After the update all components and profiles 
will be ready for CMDI 1.2 but also still available in their current 
state. New metadata instances can then be created using either CMDI 1.1 
or CMDI 1.2, even with newly created profiles. There will be facilities 
to convert existing metadata, although conversion is not mandatory as 
CMDI 1.1 will keep being supported. More information about CMDI 1.2 can 
also be found on the CLARIN website[2]. Additional information will 
become available soon after the deployment via the CLARIN website and 
various mailing lists.

If you have questions or notice problems with any part of the 
infrastructure outside this timeslot, please contact the system 
administrators (sysops at clarin.eu) or CMDI developers (cmdi at clarin.eu).

Best,
Twan
