Subject [jira] [Commented] (SIS-391) Implement OGC Catalog Service for the Web (CSW)
Date Sun, 25 Mar 2018 19:29:00 GMT


Martin Desruisseaux commented on SIS-391:

Hello Hao

The use case with a user visiting VNSC web site and searching for temperature data, daily
data, etc. is fine. But I have not seen a description of the framework you would consider
to use. You can name for example the J2EE classes extended by the GSoC 2016 prototype. Or
you can name another framework you want to consider. This is not a commitment to use those
frameworks - you can change your mind during the GSoC. This is just an enumeration of some
server frameworks that could be used for doing the implementation. I suggest to name at least
the Java classes used by 2016 prototype.

I suggest to clarify that this GSoC is mostly about the server side. An application may be
done on the client side (the browser), but that would be a side-effect; the main goal would
be the server side. You can also said that the web server application would be developed in
the Apache SIS {{application/sis-webapp}} module.

> 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.
