One of our students ( Manuel Undesser) developed as part of his bachelor thesis a UI for generating and editing the metadata of CSV files which is compliant with the CSV on the Web metadata standard.
the current early alpha status and test version is available at: http://data.wu.ac.at/csvengine/
We would be very happy for any feedback, comments, criticism, suggestions, bug reports, etc… 😉
We plan to release our editor in the near future to the public with the hope that such a tool will help to further drive the adoption of the metadata standard and ease the generation of an initial version. We will also release the source code on github after another round of testing, improvements and adding documentation.
