 title: TWG Ops Liaison
 ---
 
-The TWG Ops Liaison has these basic duties:
+The TWG Ops Liaison is a Technical Working Group (TWG) representative who serves as a liaison to the OBO Foundry Operations Committee (OFOC).
+
+Major responsibilities:
+1. Report TWG progress at OFOC calls
+- Monitor PURL, Dashboard, COB, OMO and GitHub repos for PRs and new issues
+- Collect those issues for every meeting in short digestible report (links are fine, no details needed unless pertinent)
+- Report those issues during OFOC calls
+2. Serve as a first point of contact for OFOC and OBO Community for technical Q/A
+- In Slack and GitHub issue tracker, be responsive to user requests relating to OFOC activities (PURL, dashboard, principles, OMO, COB) and direct them to the right channels
+- Help connect OFOC members who need technical help with the right TWG members
+3. Mark relevant GitHub issues for discussion during OFOC call
+- When a new GitHub issue or PR seems to need OFOC attention, label "attn: OFOC label" a few days before the next OFOC call
+- When a GitHub issue has been discussed during an OFOC call, make sure a comment to that end is added to that issue and the label removed
+4. Summarise TWG activities to OBO Newsletter steward
+- Provide a list of major activities to the newsletter steward for inclusion in the newsletter when requested, or when activities of note happen
+
+Note that the TWG Liaison does not have to be the TWG chair; therefore, the TWG Liaison doesn't need to have technical expertise. (The TWG doesn't currently have a dedicated chair because it doesn't have a regular meeting schedule.)
