4) Enumerations: changes (10 minutes)
Previous:
Status: Enumeration work is on hold until someone has the time to move it along. What follows is a summary prepared by Florido of work that needs to be performed:
a) Most of the enumerations contained in GFD.147 are missing from git-hub CSV files. They should be added. This is kind of a monkey job.
b) InterfaceName_t and Capability_t are the ones Florido and David (and every GLUE2-supported software developer in the world) should discuss. The problem is that services like GOCDB created their own names and single software created their own and sometimes they clash, i.e. an Endpoint has different OpenEmumerations representing the same thing on different systems. We should keep one of each and mark Recommended and Deprecated. Florido once made a list of those that should be summarized, here: https://docs.google.com/spreadsheets/d/1zuEiCP-0mQVJWOCGWxnKJ5p9vetLMIfN_AwF...
c) Some enumerations are hard to keep track of. Examples are operating system names, versions, distributions. It is not clear how a new operating system should be mapped to its GLUE2 equivalent. Neither is clear who should collect and diffuse this information: the GLUE2 group or the users?
d) There is an ongoing debate on how to represent protocols in general. In practice the use case is on the storage elements. They want to put such information in the InterfaceName. I would rather prefer to have it in Capabilities. Either way we will have a plethora of possible combinations of interfacenames and capabilities. E.g. a storage element that can understand three protocols should have either three Endpoints with different interfacenames for each protocol or a list of capabilities for each transfer capability and protocol. Example:
Option 1) Using InterfaceNames StorageService 3 Endpoints: myendpoint.http Capability: data.transfer myendpoint.ftp Capability: data.transfer myendpoint.sftp Capability: data.transfer
Option 2) Using Capabilities: StorageService 1 Endpoint: mystorageendpoint Capability: data.transfer.ftp data.transfer.http data.transfer.sftp

Proposed agenda with previous meeting notes from September 2015:
I'd suggest putting the cloud discussion last to make sure we get to the others - I'm particularly keen to put the LDAP rendering to bed after 7 years! Stephen
Hi, I prepared some slides for the discussion: is there an agenda where upload them? or in case I will send them to the list next week cheers, Alessandro On 10 May 2016 at 10:35, <stephen.burke@stfc.ac.uk> wrote:

Participants: Alessandro Polini, Paolo Andreetto, David Meredith, Stephen Burke, JP Navarro Skype business didn’t work for everyone so we used Adobe Connect. 1) Enumerations: changes (10 minutes) David mistakenly merged “org.opensciencegrid.htcondorce” into csv and will remove it Approved addition of org.openstack.swift to complete the openstack set Dave volunteered to “take on the enum work" 2) LDAP rendering: public comment is closed, discuss next steps 3) JSON rendering: continue rendering discussions, discuss next steps Briefly discussed status JP confirmed after the meeting that both documents were submitted for final publication in March We are currently waiting for OGF to publish them 4) Cloud Extensions (45-60 minutes) Alessandro presented slides with the proposed GLUE 2.1 Cloud Extensions: https://redmine.ogf.org/dmsf/glue-wg?folder_id=6616 <https://redmine.ogf.org/dmsf/glue-wg?folder_id=6616> Some minor questions were raised during the presentation. ACTION: We need to find the source to the GLUE 2.0 UML diagrams and a tool for updating them to add Cloud (volunteer?) If we fail to find the source we may need to recreate them because we believe they are useful to have ACTION: Alessandro will update the review GLUE 2.1 specification based on meeting feedback We discussed taking a vote to make it into an official DRAFT EGI would then implement a prototype for the FedCloud environment extracting information most likely from OpenStack and publishing in LDAP format ACTION: Agreed that JP would seek an XSEDE review and comments on the specification. ACTION: JP will contact OGF leadership on whether we should share our Cloud work with an other active OGF groups Future official approval of GLUE 2.1 would occur after the specification is revised based on prototype lessons learned Regards, JP
Hi, just a brief comment on the action:
ACTION: We need to find the source to the GLUE 2.0 UML diagrams and a tool for updating them to add Cloud (volunteer?) If we fail to find the source we may need to recreate them because we believe they are useful to have
I've asked Sergio (Andreozzi), he gave me this link https://redmine.ogf.org/dmsf/glue-wg?folder_id=18 where there are files for the glue 2.0 diagram (he stopped his collaboration after the glue 2.0 was implemented) but we still miss the original files for the cloud computing model diagrams. Moreover Sergio seems to remember to have used this application for producing the diagrams https://www.visual-paradigm.com/download/community.jsp cheers, Alessandro On 17 May 2016 at 18:10, Navarro, JP <navarro@mcs.anl.gov> wrote:
