[OSGeo-Discuss] OSGeo and Open Data?

In my opinion another relevant topic is open data and its quality, i.e. methods and tools for assessing open data quality.

Some data has metadata quality, some data has not.

Before using them we have to be sure that the characteristics of the data fit our exigences. For instance open data are useless if they are not updated or they are bad quality.

Therefore, I would add to your list

 Methods and FOSS tools for assessing open data quality.

Oggetto: Re: [OSGeo-Discuss] OSGeo and Open Data?

I think there is a very strong connection to make between open-source and open data.

Open Data is a broad concept that really means "access to data". Access is more than just a download, or a license - it also means having the tools and methods available for everyone to turn the data into something which is relevant to answering specific questions.

It also means that data are available in accessible formats - ones that anyone can use without restriction. Though that's not the same as 'a standard'.

Regarding the Public Geodata Committee, it's worthwhile to consider what unique role OSGeo can provide to improve the global and local situation. There are numerous catalogs of varying states of quality and maintenance - so it's unlikely a need to have yet another catalog.

However a few issues that are open questions and could be interesting to work on and beneficial to the broader community:

- Geospatial support of common data catalog formats. Notably DCAT has become prevalent thanks to the development & adoption of CKAN by many national governments. The spatial capabilities are nascent, so what would OSGeo recommend as better practices. Maybe also consider open-source implementations of DCAT publishing and consuming libraries so that more tools (e.g. QGIS) could publish or search and consume from DCAT-capable catalogs
- Guides and Patterns for data analysis with spatial tools. What open-source libraries exist that enhance general data analysis tools such as R, Python, etc. What are the practices for someone new to geospatial who are using these tools find and incorporate geodata into their work?
- Geospatial data formats advocacy. Stefan Keller is well known to pop up in any discussion of the Shapefile to tout the benefits of Geopackage. Can we vet that hypothesis and advocate for more geospatial tools to produce & consume modern formats like Geopackage?

Having spent the past 10 years focusing my open-source development efforts specifically on the publishing, discovery and exploration of open data I'm a bit excited about the topic :)

Nobody in his right mind would want Open data out of OSGeo and least of all Jeff.
Yes, we must find a way to reactivate the Public Geodata committee. Perhaps
renaming it as Open Geodata committee would be a start. We also have a new
"Open Geoscience Committee" [1]  with great work being done in longterm
archiving of FOSS4G videos, for instance.

What I would suggest is to strengthen tie-ups with OSM,  HOT and perhaps consider
building something like Data4All, emulating the success of out educational outreach,

Hi Jachym,

I have given talks on OSGeo and open data.  I am sorry to hear that you
believe I said that about the foundation.  I do believe we've discussed
this in face-to-face board meetings before, so maybe that is where you
heard this?  I remember a discussion of adding open data into our
foundation's mission statement, which I believe we did.

Hi Sanghee,
I was told some months ago (and I believe, it was Jeff), that we
(OSGeo.org) are solely software foundation - therefore we do not care
about open data

maybe things have changed?

    Dear all,

    Can anybody share presentation file about the OSGeo and open data,
    if any? I'm invited to give a keynote talk at 'Open Data in Action
    Conference'[1] in Korea and I don't want to make the file from the

    FYI, OSGeo Korea[2], R Korea[3], Open Data Institute(ODI) Seoul[4],
    Open Knowledge(OK) Korea[5] will co-host the event on 15th Nov near
    Seoul. The main theme of the conference is 'Experiment on Open Data
    based Society.' Anybody who has similar interest can join this

    Kind regards,
