Apache SIS provides an implementation of geospatial metadata as modeled by ISO 19115 international standard, together with its representation in XML (ISO 19139). This metadata support has been used in a previous Google Summer of code project (by Hao in 2016), as a part of task SIS-307. This project resulted in two main parts:
- A reader capable to provides GeoTIFF information in a structure compliant with ISO 19115 standard.
- A prototype of Catalog Service for the Web (CSW) – done with the help of Chinh – following the standard published by the Open Geospatial Consortium (OGC).
The GeoTIFF reader, which was the main topic of Hao's work, has been integrated in Apache SIS, together with her reader for Landsat metadata. However the CSW part, which was a prototype, is not yet ported into Apache SIS but is available on Hao's repository on GitHub. We propose a Google Summer of Code project for continuing Hao's work. The goal is to provide a fully functional CSW to be integrated into Apache SIS. This work will use Hao's GeoTIFF and Landsat readers, together with other readers available in SIS: netCDF, Moving Features and GPX formats.
