Flickr has enabled machine tagging quite some time ago and there has been a general push in the web towards semantic relations and data structures (e.g. see the archive posts on the Music China Heritage Project). However there seems to not have been a comprehensive “Quick to use” list of common machine tags that photographers and Flickrites can use. In fact while finding a number of high-ranked explanatory posts about the nature of machine tags, I have not found a brief overview of what I (as a typical photographer) can do to enhance my photos.
General tags applicable to most or all photos:
location:city=* (e.g. Stuttgart, Beijing, New York, etc.)
location:country=* (e.g. Germany, France, etc.)
Every photo is being taken somewhere, and hence the content of the photo has been taken at the LOCATION as specified. Machine tags like these are nice add-ons, while Flickr itself takes the EXIF information to place the photo on the Flickr Map.
wikipedia:en=* (e.g. Paris, Banana, etc.)
This will create a link between the photo and the wikipedia page that is mentioned here. Be aware to NOT enter the whole wikipedia link, but only the title of the page that you are refering to. E.g. a photo representative of Paris should be linked to Paris. But if you have a photo that shows the Eifel Tower it might be better to link that to the Wikipedia article of the Eifel Tower and NOT Paris.
For buildings / architecture photos:
architecture:building=* (e.g. Airport / cathedral / church / etc.)
architecture:completed=* (requires a year, e.g. 2015)
airport:iata=* (if the photo is taken inside an airport or depicts a part of an airport, then you can assign the IATA code here, e.g. FRA for Frankfurt International Airport).
For flower / plant / animal lovers:
taxonomy:kingdom=Animalia (for animals)
taxonomy:kingdom=Plantae (for plants)
taxonomy:binomial=”* *” (replace the stars with the genus and species)
Information for individual species can be found at Wikipedia. The Flickr group EOL has more information on how they use machine tags.
For Music / Band Promo Shots / Events such as concerts/festivals:
event:type=* (e.g. concert, festival, fair, musical, opera, etc.)
event:venue=* (requires a specific name, such as CGGB or House of Blues Chicago)
music:artist=* (Name of the artist. Be aware of the differences between ARTIST, MUSICIAN and ROLE)
music:band=* (Name of the band, such as Slipknot, Metallica, etc.)
Musicbrainz, one of the large music directories online, has assigned a specific ID for artists, CDs, tracks and labels. On their explanatory page they offer a ay to identify this ID on their website.
foursquare:venue=* (see here for explanation)
Colors / Concepts:
For photos that are more minimalistic in their approach one has the option to include descriptive tags such as:
abstract:shapes=* (e.g. dot / circle / grid / lines)
color:contains=* (e.g. blue / green / yellow / etc.)
Summary and Updates:
- This should be a handy guide for Flickrites to tag one’s own photos with appropriate machine tags.
- If you have further tags that are useful, please add them as comments and I will include them in the list.
