Mime type for files about api

[JanKoppe]

I've started documenting this in #18. A PR for a implementation in muncher exists, though the code is extremely basic (recognition only based on file extension, not actual content).

We would need to properly define the mappings between file extension and reported MIME types. Right now scripts (e.g. R scripts) are reported as application/octet-stream, though interpreting them as text/plain would make much more sense.

Here is a list of files we want to display (for now; each bulletpoint should have its own MIME type):

• svg
• geotiff
• all other image files which can be displayed via <img>
• video files
• audio files
• .csv files
• everything else will be displayed as plain/text
• RData might be displayed differently

custom mime types can be configured in this file in the muncher: https://github.com/o2r-project/o2r-muncher/blob/master/config/custom-mime.json

@jansule Can you please check files from your list and clearly mark which ones do not work yet?

[jansule]

File types successfully tested:

• application/pdf
• all other image files which can be displayed via <img>
• everything else will be displayed as plain/text
• svg
• geotiff
• video files
• audio files
• .csv files
• RData might be displayed differently (how? call head in an R session?)
• markdown
• RMarkdown - treat specially?
• shapefile

@jansule prepares an example compendium with all potentially relevant file types

@jansule Please update the list of files that have not been tested yet here. And feel free to create an example compendium with all file types as part of o2r-muncher (in test/bagtainers).

Thanks!

@jansule please update!
