May I know which kind of datatype is to be added and to support what type of data?

This is a message posted to all tasks under "Need Discussion" at Possible-Tech-Projects. Outreachy-Round-11 is around the corner. If you want to propose this task as a featured project idea, we need a clear plan with community support, and two mentors willing to support it.

This is a message sent to all Possible-Tech-Projects. The new round of Wikimedia Individual Engagement Grants is open until 29 Sep. For the first time, technical projects are within scope, thanks to the feedback received at Wikimania 2015, before, and after (T105414). If someone is interested in obtaining funds to push this task, this might be a good way.

this discussion has raised the usefulness of a degrees-minutes-seconds datatype for angular information.

The quantity datatype can fulfill that well once precision and custom formatters are supported properly.

I don't know if that's true. Right ascension is peculiar - it is typically given in time units (hours, minutes, seconds, and decimal beyond that). Formatting could turn a numerical value (number of seconds, say) into the right sort of string, but how do you handle data entry? Ideally we want somebody to be able to type in values as they find them in an astronomical table, which would be in the hours-minutes-seconds format, not a numeric number of seconds. Is there any proposal to create a data entry formatter that could do that sort of thing?

IMPORTANT: This is a message posted to all tasks under "Need Discussion" at Possible-Tech-Projects. Wikimedia has been accepted as a mentor organization for GSoC '16. If you want to propose this task as a featured project idea, we need a clear plan with community support, and two mentors willing to support it.

This is an Epic task with a lot of blockers. Does this as a whole fit the criteria for a 3 month GSoC '16/Outreachy internship ? or do the sub-tasks can be made into full-fledged candidates for Possible-Tech-Projects . Thoughts?
Note that a GSoC/Outreachy project should not take more than 2-3 weeks for a senior developer to complete
