Steal this presentation!

Open data is information that is available for anyone to use, for any purpose, at no cost.

Good Open Data

• can be linked to, so that it can be easily shared and talked about

• is available in a standard, structured format, so that it can be easily processed

• has guaranteed availability and consistency over time, so that others can rely on it

• is traceable, through any processing, right back to where it originates, so others can work out whether to trust it

From Open Access to Open Data

Documents are not enough

http://datadryad.org/

http://thedata.harvard.edu/

http://www.data.gov/

http://www.ecuadorencifras.gob.ec/

Any institution could publish open data

Specially big institutions

http://data.un.org/

http://www.nodc.noaa.gov/OC5/WOD/pr_wod.html

http://www.iode.org/

Where to find Open Data?

http://datahub.io/

http://www.re3data.org/

http://databib.org/

http://www.datacite.org/

Sounds good… What to do to open my data?

Three guidelines

• Keep it simple

• Engage early and often

• Address common fears and misunderstandings

Four Steps

• Choose your dataset(s)

• Licensing

• Make the data available

• Make it discoverable

Chose Dataset

• Asking the community

• Cost basis

• Ease of release

• Observe peers

Licensing

Data that doesn’t explicitly have an open license is NOT open data.

Ownership

• you get copyright over works (content) that you create and which are original to you, such as text that you write or photographs you take

• you get a database right over collections of data that you have put a substantial effort into obtaining, verifying or presenting (only EU, Mexico, Brazil)

Open Licenses Creative Content

Open Licenses for Databases

Make the data available

Technical Availability

• Data should be complete

• In a (open) machine-readable format

• It should contain metadata

How to make it available?

• Your website

• Existing repositories

• Creating your own repository

Open Data Repositories

• Similar to Open Access Repositories

• Metadata support is different that for documents

• Should support different types of data

http://ckan.org/

http://github.com/datadryad

Making it Discoverable

• Publish it in Public services (Datahub)

• Index it in Catalog (Databib)

• Promote it in your community

• Engage with users

Conclusions

• Open Data is the new movement among Open Access movement

• Mature enough to start using/contributing• It is more a political than a technical decision

at this point• Main issue: Why it is valuable for me?
