Readers/Structured Data

The Structured Data team in the Wikimedia Product department at the Wikimedia Foundation builds features that use and allow creation of structured data associated with MediaWiki pages.

ProjectsEdit

The team is currently focused on the Structured Data Across Wikimedia (SDAW) grant-funded program. Previously, the team's main project (from August 2017 to Dec 2019) was Structured Data on Commons.

Projects in the SDAW program include:

We mostly work on the following extensions:

Inactive and semi-active projectsEdit

Some members of the team were involved in development on these projects (when we were called the Multimedia team). They are not actively involved at the moment, but might be able to help if you have a question:

Team DocumentationEdit

Team process/working agreementsEdit

  • We deliver features incrementally.
  • If the acceptance criteria of a phab ticket change (for example as a result of discussion in the ticket's comments), the ticket description is expected to be updated to reflect the change.

Phabricator BoardsEdit

  • The Current Work board is for in-progress development. It is managed by the team as a whole.
    • Each column on the Current Work board should be in order of priority, from most important at the top to least important at the bottom. Tickets should automatically be added to the bottom of a column unless it is urgent or high priority, when it can be added to the top.
    • Columns on the Current Work board include:
      • Incoming: Where tickets automatically when added to this board.
      • Epics: Reflective of the big projects the team is currently working on.
      • Needs Design: Tickets that require input from the designer.
      • Needs CL: Tickets that require input from the Community Liaison.
      • Ready for Estimation: Tickets that require estimation.
      • Ready for Development: Tickets that are ready to be worked.
      • Blocked: Tickets that are blocked, from outside the team or until other work is complete.
      • Doing: Tickets that are currently in progress.
      • Design QA: Tickets that require approval from the designer.
      • Code Review: Tickets that require code review.
      • Needs QA: Tickets that require QA in beta.
      • Verify on Production: Tickets that require QA in production.
      • Deployment/Config: Tickets that require deployment outside of the regular train schedule.

Daily WorkEdit

  • Each day, within the columns relevant to you, and for the tickets you feel qualified working on:
    • Work through columns from right to left:
      • insofar relevant, validate things in “Needs QA”;
      • then review tickets in  “Code review”;
      • then continue whatever you already have in “Doing”;
      • then verify whether tickets in “blocked” are, in fact, still blocked;
      • then pick up new work from the top of “Ready for Development”.
  • Within each column, work from top to bottom, picking up the first (highest priority) ticket you feel qualified to work on.
  • Update all tickets as soon as you do something that changes the state of that work, e.g:
    • As soon as you pick up work, assign yourself & move into the relevant column
    • When merging a patch, move the relevant ticket out of “Code review”
    • If you do anything that is not 100% self-explanatory (and actions rarely are) then a comment on the ticket should accompany every action taken.

Regular CommunicationEdit

  • When appropriate, have conversations in a visible Slack channel (e.g. #sd-eng or #structured-data), so that others can follow along if they’re interested.
  • Any outcomes or decisions from conversations that impact the team, either publicly on Slack or in smaller venues, should be shared with the team publicly and documented in the relevant Phabricator ticket.
  • Standup (every day except Friday):
    • Every team member posts standup notes in the #sd-standup slack channel.
    • In addition to stating what you’re working on:
      • Share any relevant information you learned about, that can be delivered in a short update without too much context. E.g.:
        • “Team X has done Y, which should help us for Z”
        • “Deployment didn’t go through so our feature is not yet live”
        • “I attended X meeting, and Y was the outcome”
    • Post any big interruptions as soon as you are able to communicate it, and once again when it actually happens (e.g. vacation, on another project for a good part of your time, parental leave).

Creating New TicketsEdit

  • All members of the team can create new tickets at any time. There are templates in the menu of the backlog to assist with this.
  • New tickets should be tagged with the #structured-data-backlog tag, which will put it in the “needs triage” column of the backlog, to be attended to at backlog grooming.
  • New tickets should contain a user story, as much description as possible, and as much acceptance criteria as possible. Anything you don’t know at the time can be added later, but should be added before estimation.
  • If a ticket is urgent, it can be added directly to the current work board to the appropriate column, but the team should be alerted via Slack.
  • Spin-off tickets that are essentially part of another ticket (that has already been groomed) but are tracked separately for technical reasons (e.g. requires changes across multiple extensions) can also be added directly to the current work board in the appropriate column. However, if it is new work, it should be added to the backlog and put through the process. Spin-off tickets should not require estimation, since theoretically the work is part of another ticket that already has an estimate.

MeetingsEdit

  • Backlog Grooming (every Monday):
    • Attended by the tech lead, designer, QA (optional), PgM, and PM.
    • Review each column on the current work board, from right to left, to see if anything needs to change based on circumstances or priorities. If so, move the ticket and inform the team.
    • Review the “needs triage” column on the backlog.
      • Ensure that each ticket has the necessary detail and full acceptance criteria.
      • Discuss the priority of each ticket, and move each ticket to the appropriate column in the backlog, or to “Needs Estimation” on the Current Work board, in priority order.
    • Discussions outside of backlog grooming tasks should not be held in this meeting, because it decreases visibility to the team.
  • Project Meeting (every other Tuesday):
    • The entire team attends this meeting.
    • This meeting is used to build shared understanding, and is dedicated to catch all of us up on where we are right now and what we expect the short-term future to look like. This is a great venue to raise questions or issues before they become blockers.
      • Other topics at this meeting can include sharing designs, discussing individual decisions or ideas, or ironing out acceptance criteria on tickets that require discussion.
      • Anyone can add topics to discuss at this meeting in the agenda document linked in the calendar invite.
  • Retrospective (every other Tuesday):
    • The entire team attends this meeting.
    • This meeting is used to reveal kudos and facts or feelings that impact the team, and discuss any proposed improvements or solutions. The retro should focus on actionable change, which means sometimes deeper conversations should happen after.
  • Estimation Meeting (every other Wednesday):
    • This meeting is used to estimate tickets in the “Ready for Estimation” column.
    • The team estimates the tickets in the "Ready for Estimation" column using t-shirt sizing.
    • Once estimated, tickets are moved to the Ready for Development column. By default, tickets are moved to the bottom of the Ready for Development column, unless they are urgent or high priority, in which case they go at the top.
    • If something needs to be estimated more urgently than every two weeks, we can hold an async estimation on Slack in the #structureddata channel.
  • Office Hours (every other Wednesday):
    • This meeting is attended by team engineers. Others are also welcome to join, if they want to discuss or learn about technical topics.
    • The purpose of this meeting is to have a venue to discuss technical topics.
  • Tickets are moved to the Ready for Estimation column when their design and acceptance criteria is complete and they are ready for work.

Code reviewEdit

As a general guideline, developers ought to start the day with up an hour of code review.

When something is ready for review, add other devs as reviewers. If something is not ready for review, you ought to indicate that with a [WIP] tag or a -1
