Action Items

(AI) Keith Hazelton and Ann West will edit the appropriate pages to make clear that URLs are as good and possibly better than URNs for entitlement values, etc. They will also add a page to the wiki that makes the case for URLs over URNs.

(AI) Steve Carmody will edit the Best Practices Working Group charter, incorporating the comments and the wiki page, and send a note to the TAC email list when he has finished the editing.

(AI) Steve Carmody and Nick Roy will recruit non-usual suspects to join the Best Practices Working Group. We need to make sure that these baseline practices are achievable for smaller institutions.

(AI) At its next meeting, TAC will review the R&S Migration Strategy, confirming the consensus that InCommon should follow Option #1 on this wiki page:

(AI) Tom Scavo will summarize the consensus of TAC members with respect to the REFEDS R&S migration strategy.

Per-Entity Metadata Pilot

Tom Scavo reported that we will continue to operate the server, given that LIGO and UW-Milwaukee are using it in production for eduGAIN. This will also allow the next iteration of the Metadata Distribution Working Group to spin up and determine whether this will become a full production service. See the per-entity metadata report on the wiki.

URNs vs URLs

Keith noted that MACE-DIR is receiving a number of requests for URNs (rather than URLs). He asked TAC to consider the question, “Should we be doing more to promote the use of URLs in preference to URNs in situations where InCommon (and Internet2) recommend the use of URNs or URLs to guarantee global uniqueness of values?” (See There is a wiki page that advocates URLs but does not provide a rationale.

There was consensus that we should promote URLs over URNs. (AI) Keith and Ann will edit the appropriate pages to make clear that URLs are as good and possibly better than URNs for entitlement values, etc. They will also add a page to the wiki that makes the case for URLs over URNs. This does NOT mean we’re deprecating or trying to purge URN-based values.

Strawman: 2015 Goals

Steve discussed the 2015 goals sheet that he distributed earlier via email. The Steering Program Subcommittee is in the process of setting priorities based on this strawman. TAC members have been asked to review the document and send their choice for the top five InCommon priorities for 2015 to the TAC email list.

Draft Charter for the Best Practices WG

TAC discussed and reviewed the draft charter for this working group ( There is already consensus among TAC and Steering that developing these practices will be a 2015 priority.

TAC voted to approve this working group and charter.

(AI) Steve Carmody will edit the charter, incorporating the comments, and send a note to the TAC email list when he has finished the editing.

(AI) Steve and Nick will recruit non-usual suspects to join this working group. We need to make sure that these baseline practices are achievable for smaller institutions.

Registered By InCommon Category

There was discussion about adopting and operationalizing the “Registered by InCommon” category, which would allow identification of the registration authority. This is recommended by the New Entities working group and was discussed here two weeks ago. A description of the category is here:

(AI) Steve Carmody will provide a summary of this category and its implications to Steering as an informational item.

REFEDS R&S Migration Strategy

There was discussion of the InCommon migration strategy for the REFEDS R&S category. Tom Scavo has added a third migration option to an existing wiki page:
There was discussion about what we are trying to achieve. If we’re going to have all IdPs do some work, for instance, we should end up in a better state at the end (for instance, that the legacy InCommon-only R&S entity would be removed from metadata). There was support for that viewpoint from TAC. Also, that InCommon messaging should encourage the adoption of the international category.

There was general consensus for Option #1 on the R&S Migration Strategy wiki page, but TAC will review this again at the next meeting before making a final decision.

ECC Certs

Jim Jokl discussed the need to create profiles for ECC certs and is spinning up the Wednesday calls in the next week or so. Scott Cantor said that he would do software testing once the group has something developed.
