3. ESA-wide policy on Open Source Software (OSS)
Objectives: Improve ESA governance on Open Source Software procurement, according to technical needs, covering licensing aspects and the establishment of clear guidelines and procedures for OSS transfer outside the MS.
An ESA inter-directorate OSS Taskforce was set up in 2010 and recommended the OSS policy
OSS Policy was approved in Sep-2011
Justifications:
For ESA space programmes OSS can provide cost savings and innovation.
For industry it can provide ways to enter the market (in particular for SMEs) and
cost reduction for development and maintenance of software products and tools.

4. ESA’s OSS Policy – Key points
Authorise the use of Open Source Licensing as legitimate, technically valid and a legally sound options for ESA software developments in the following cases:
Collaboration with Universities and Research Institutes;
Promotion of space international standards;
Mission Data Processing tools;
Engineering Tools;
Industrial Commercial Interest.
Definition of OSS Procurement Guidelines (updates of ESA’s General Clauses and Conditions for ESA Contracts)
Implementation and maintenance of an ESA OSS Repository for ESA wide use and support to industry

5. OSS In practices
In line with the spirit of the free and open data policy, ESA’s Earth Observation ground segment department is committed to develop more and more open source software.
Affected domains:
EO tool boxes
Multi-mission components of ground segments infrastructures
EO data Processors
Operational software in general
Software developed in R&D
Contribution to OGC, WGISS
Earth Science Exploitation platform
Many Open Source software released in the past
Open Source software contribution will increase in the future

7. Software & Open Sources Practices at ESA – Today & Tomorrow
The European Space Software Repository (ESSR) is an ESA information web portal to promote reuse of Software including Open Source Software (OSS), and provide all parties involved in European Space software development access to results of previous investments.

8. ESSR Objectives The ESSR objectives are: What can it do?
Guide European Space Industry in identifying available OSS
Allow Industry to make their OSS products and associated services known to the space community and beyond
Help European industry in joining ongoing OSS collective development projects;
Provide visibility on licensing schemes and legal aspects on European products
Support building up of collaborative OSS initiatives
What can it do?
The ESSR web portal contains a list of projects, search function (e.g. using tags) and blog functionality among others.
The projects contain general information (name, description and a link to a more detailed information page), creation and last modification date, version control system, owner and license type information as well as a homepage and download link. Users are either Guest or Registered, with different access level. The registration process is handled by the tool.

9. OSS discussion triggered by …
OSS in CEOS WORK Plan

10. OSS in CEOS – First clear change
In order to reflect the updated structure the Open Source Software page should be moved into Interoperability and Use Area

11. OSS in CEOS – Way Forward
Create a dedicated web page in WGISS  Interoperability & Use
OPEN SOURCE SOFTWARE
List of the Open Sources Software
Data Product generation …
Quality control
Data and Metadata Management
Data Analysis
Visualisation & Valorisation
Open Data Cube (with all relevant metadata – agency, description, version, application
area, downloading link – OR direct link to the Agencies relevant
repository, Github, etc.)

12. OSS in CEOS – Next Steps
OSS Survey in CEOS Agencies compiling the reports with relevant Metadata

13. OSS in CEOS – Next step to be discussed
ACTION: Create a Repository of OSS (but not exclusively) in CEOS WGISS
Two Options:
Physical Repository in CEOS with
OSS managed by a CMS.
Mixed Repository in CEOS with reference link to
CEOS agencies Repositories and software
uploaded.
