 The new SPB platform is a fully integrated environment,
-being very advanced in comparison with related projects and initiatives.

 For instance, the USA government has a platform designed to improve access to
-the federal government developed software\footnote{\url{https://code.gov}}.
-Code.gov is an interface to organize the USA government projects and, in short,
-make it easy for users and developers to obtain information and access their
-source code repositories at GitHub. However, there are not social networking
-and CMS features, as well as, other communication resources provided by that
-platform.

 Additionally, there are two initiatives in Europe:
 OSOR\footnote{\url{https://joinup.ec.europa.eu/community/osor}} and
 OW2\footnote{\url{http://ow2.org}}. The Open Source Observatory (OSOR) is a
 community hosted in the JoinUp platform powered by the European Commission.
-OSOR aims at exchanging information, experiences and best practices around the
-use of FLOSS in the public administration. It helps to find a FLOSS made
-available by other public administrations, providing access to information such
-as news, events, studies and solutions related to implementation of open source
-software. It also offers forum discussions and community mailing lists, but it
-does not have an integrated source code repository manager and for the each
-project there is a link to its own external repository (or its tarball file).

-OW2 is a FLOSS community to promote the development of FLOSS middleware, generic
-business applications, cloud computing platforms and foster a community and
-business ecosystem. In short, it aims to support the development, deployment
-and management of distributed applications with a focus on FLOSS middleware and
-related development and management tools.
-
-Moreover, in 2007 the European Comission published a study examined the impact
-the development and distribution of FLOSS by public bodies has on eGovernment
-services, the economy, and the information society \cite{ghosh2004}. And there
-was between 2007 until 2011 the QualiPSo project that aimed at providing FLOSS
-users, developers, and consumers, with quality resources and expertise on the
-various topics related to FLOSS. The QualiPSo project also had planned to
-develop a platform called QualiPSo Factory but it was not fully completed.

 Finally, in Latin American there is an initiative based on the SPB project
-called ``Software Publico
-Regional''\footnote{\url{http://softwarepublicoregionalbeta.net}}. From a
-practical point of view, it provides a customized Gitlab instance to share the
-source code and documentation of the project from the involved countries.

 The Brazilian government needed to evolve the SPB platform that existed since
 2007. When we started this project, the SPB Portal had about 200 thousand
-registered users. For example, we could not just contact these users and ask
-them to register an account at Github as well. Moreover, after the Edward
-Snowden's case, the Brazilian government approved a specific law decree
-(8.135/2013) to rule its communication services, requiring the public
-administration to host its information systems to be provided by itself, what
-rules out usage of private platforms, specially ones provided by foreign
+registered users. We could not just do something like contacting these users and asking
+them to register an account at Github. Moreover, after the Edward
+Snowden's case, the Brazilian government issued a decree
+(8.135/2013) requiring public
+agencies to host their information systems by themselves, 
+avoiding the usage of private platforms, especially the ones provided by foreign
 companies. Therefore, we needed to develop our own solution to cover all the
 requirements, producing a complete governmental integrated platform for
 collaborative software development.
