A Project Steering Committee has been formed and it is now used to make decisions for the software project. (See: http://wiki.orfeo-toolbox.org/index.php/Project_Steering_Committee and http://wiki.orfeo-toolbox.org/index.php/Summary_of_PSC_Decisions)

Update: (2015-07-24) A Project Steering Committee has been formed. Management decisions are now made in a standard way. Details on the Project Steering Committee can be found at http://wiki.orfeo-toolbox.org/index.php/Project_Steering_Committee.

  1. Does the Project Steering Committee have documentation on project procedures for PSC decisions, contributor guidelines?

In early 2015, OTB set up an official Project Steering committee (PSC) to provide high level guidance and coordination. It provides a central point of contact for the project and arbitrates disputes. It is also a stable base of institutional knowledge to the project and tries its best to involve more developers and guarantees that OTB remains open and company neutral. The OTB PSC was inspired by existing structure which exists in other geospatial software projects like GRASS GIS, GDAL or QGIS.

The documentation about how the governance works in general and hopw decisions are made is publicly available in the OTB PSC status page. All the decisions regarding OTB are also public and follow a procedure called RFC (Request for Changes) which is also describes in the OTB wiki.

A Request for Changes describes a change in Orfeo ToolBox code, API, infrastructure or processes in general that need to be submitted to the PSC vote. Those elements should be provided in an email to the public OTB developer list, with subject starting by "Request For Changes: ".

The list of all Request for Changes is maintained and publicly available on the OTB wiki.

The PSC status gives also information about contributor guidelines and also in particular how new commiters or PSC members can be added to the project. Like other decisions, it would be done with an RFC on the mailing list, a public discussion, a then a vote.

The OTB website gives also more information on how to contribute to the project.

OTB was created from its inception as a collaborative, community effort. As many open source projects there are number of ways to participate which do not all require programming capabilities: documentation, bug reports and feature requests are all very valuable.

  1. How many active developers are there? Are they from multiple organizations? Indicate number and some organizations involved.

The ohloh page of the Orfeo ToolBox provides a comprehensive view of contributors activity:

http://www.ohloh.net/p/otb/contributors?sort=latest_commit

There were around 15 committers over the last year.

The "Contributors" chapter of the Software Guide gives a complete listing of all contributors and their affiliations from the beginning of the project :

http://orfeo-toolbox.org/SoftwareGuide/SoftwareGuidech35.html#x64-52100035

Very active users and occasional contributors include:

  • Jordi Inglada from CESBIO/CNES is the creator of OTB and as such wrote a lot of OTB code in the past. He still actively uses and promotes it, with a lot of client codes, testing, bug reports, phd and intern works ...
  • Gregoire Mercier from Télécom Bretagne wrote the entire wavelet transform code as well as other codes, and currently has a phd working with OTB,
  • Angelos Tzotzos from National Technical University of Athens is actively packaging OTB for OpenSuse. He also contributed code for a pan-sharpening algorithm and integrated some OTB in the Gnorasi project,
  • Agustin Lobo, who I believe is with CSIC, is a very active user that benchmarked some of OTB functions and makes insightful comments on improving documentation for instance,
  • Julien Radoux (UCL) has contributed some algorithms by the past and is still very active on the users list,
  • Emmanuel Christophe, currently with Google, who wrote a great deal of OTB code by the past, under CNES and Crisp affiliations.

Foundation Membership

  1. Have project documents been updated to reflect membership in the foundation, and the relationship of the project to the foundation? If not, indicate when this will occur.

The project documentation has been modified to reflect membership in OSGeo.

  1. Has an effort been made to brand the project web site with OSGeo foundation web styling and branding marks? If not, indicate what is planned.
