The metadata problem
2026-09-02 , Ran1

In this talk, I'll try to explain the metadata problem in geospatial data and why things like STAC are useful but cannot always solve your problem.


The famous work Metaphysics belongs to Aristoteles.

For sure, in philosophy, there are always discussions. According to common acknowledgement, the book's title was given by Andronicus of Rhodes as "ta meta ta physika." In ancient Greek, this literally translates to "the [books] after the physics [books]." It wasn't a profound philosophical title; it was essentially a librarian's organizational sticky note. "Meta" simply meant "after."

For sure, some would disagree, but this snippet of information tells us something. Metaphysics is mostly perceived as knowledge beyond physics, has been mystified and even neglected in favor of positive science. But the term "meta" is mostly used to mean something of something, such as metadata, which means data about data. Therefore, it can be about physics of physics as well. The question is then, what is metadata? Data about data or data beyond data?

In this talk, I'll try to explain the metadata problem in geospatial data and why things like STAC are useful but cannot always solve your problem. We'll see the data about data and beyond by understanding the origins of geospatial data and the tools that explain it better.

By the way, many people think Aristoteles didn't write anything in his life, but that's not what this talk is about. I'm also not an expert in either philosophy or geospatial. I'd like to conduct random readings and will present my findings.
