10    gis              A geographic information system (GIS), geographical information system, or geospatial information system is any system that captures, stores, analyzes, manages, and presents data that are linked to location(s). In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.                                                                                                                                            
10    wikipedia        Wikipedia is a collaboratively edited, multilingual, free Internet encyclopedia supported by the non-profit Wikimedia Foundation.                                                                                                                                                                                                                                                                                                                                      `enter preformatted text here`

As I see it, there are several classes of tags:

  • Requests (data, APIs, tools, etc.)
  • Data domains (usa, government, data.gov, city, etc.)
  • Subject areas (maps, census, geospatial, gis, etc.)
  • Process (releasing data, best practice, file format, etc.)

That's not a bad description of what the site seems to be about, but the tags are disorganized. For instance, it's none too clear how questions are divided among , , and . I suspect they should be synonyms in the context of this site.

When I looked at the recent sample of questions, it struck me that many of them are undertagged. Take, for instance, Congressional Record in electronic form, which is tagged . It seems to me that it's a for . It might also be asking for and , but those are ambiguous tags so I can't be sure.

Tagging is the canonical example of a folksonomy, but that doesn't mean we can't define some guiding principles. How should tags be applied on Open Data?

This is a first comment. I will probably update the answer with other as well.

About the tags: , and . I could say that map is related with applications using a map. Something that has already built and not the data per se. For example a question like this one: "Where can I find a map with live car accidents in the world using open data?" The other two tags, I could say that they are synonyms and we should use one or the other.

I just finished a little spring cleaning with regard to our tags.

Currently I see two major problems:

  • There are still (too) many questions that are undertagged and/or mistagged.

  • There are still many tags that have no description, are ambiguous, redundant (like your geospatial example), or keep getting applied the wrong way.

There have been a few discussions in the recent months, but not nearly enough.

I invite everyone who notices problems with tags to fix them, flag them, or ask a new question here on Open Data meta. This needs to be a community effort, and every edit counts :)
