Delorean
The idea for Deloran came after realising how hard it is to work with temporal data, especially with aixm and how empty the opensource landscape is for such tools.
Delorean's goal is to facilitate the use, exchange and structuring of temporal data, it's goal is to be used in conjunction with QGIS and POSTGRES.
- Stage 1 will demonstrate the implementation of xsd defined schema that can convert seamlessly from xml to postgres and inversly
- Stage 2 will add temporality tools that will allow diferenty types of temporal checks, tools and methodes
- Stage 3 will create a QGIS plugin to simplify the everyday use with temporal data
- Stage 4 goal is to abstract away from a specific schema and allow custom xsd defined schema to be used as data schema with temporal structures
Documentation
Temporal feature structure can be layered in insert number layers that each allow more but comme with an addition cost in complexity:
Layer 0 Data has no temporality associated with it
- Data is indefinitly Valid
- Changes are instantenious
- Exports are snapshots
