In short, this is what my PhD thesis is about:

metadata /ˈmɛtədeɪtə/
data that describes other data.

The full story, however, is a bit more complex. I wrote something about data. This little website is about this something. The excerpt consists of:

• a categorization of data structuring methods
• a pattern language of structures in data
• details about the publication of my PhD
