topo (from Greek τοπο-, a combining form of τόπος place)
Topotime is a digital humanities project aiming to join Place and Period (space and time) in conceptual models, data formats, and software for geo-historical research. We are developing an experimental extension to the GeoJSON data format standard, and open-source software to utilize it.
The project's planned work products include:
- GeoJSON-T (repo), adding temporal ("when") elements to GeoJSON, making it suitable for representing
- attestations of historical geographic movement, such as journeys, routes, and flows (e.g. of commodities, people, or information)
- historical gazetteer records
- historical periods
- Linked Places (repo), a web application featuring (at the moment) a web map linked to a traditional timeline. The next phase development will add temporal geometry visualizations and some basic network analysis and visualizations.
- topotime.py (soon), a Python package that reads GeoJSON‑T data and can (a) generate and analyze temporal geometries; (b) perform basic network measures
All of these are either in active development or design, so the contents of this repo are dynamic "works-in-progress." Comments, suggestions, and reasonably polite brickbats are welcome.
Documentation will be maintained on the Topotime project wiki
