2012-12-11 Today, I've been at FIZ Karlsruhe to meet Frank Schwichtenberg. We spent a fine time together, talking about XML and the world around it and everything that is related to it. When he explained the core structure of their software product eSciDoc, the used the terms `item' and `container' and described meta data and further stuff. In the end, it looked just like `regular file' and `directory' and inodes and references, i.e. the good old Unix file system. He agreed and even pointed out that one of the most annoying problem they have lies in a part where their concept diverted from Unix's file system structure. It was just too nice to see the old concepts appear again and again. My interest for the XML world is low, because it collides with the Unix world. Nonetheless I acknowledge that the (pure) XML world is consistent and self-contained. It also has tools, which filter data like the Unix tools do. This shurely sounds appeal- ing. Eventually, I'd conclude: The XML world is like the LISP world, is like the Unix world -- each of them, but only one of them, can be your (pleasant) home. Frank shared some good points of view with me. He also gave me some hints to understand the XML world. The time with him was re- vealing. btw: His website is unusual.
