Welcome to the IKANOW community edition (Infinit.e) github wiki!

The web site describing the IKANOW community platform platform is here. We're currently "in between" developer forums, we can be contacted via the github issues page or at

This includes instructions for using yum to download the binaries generated from the sources maintained here: yum install details. Note the recommended URLs for the yum repositories have changed as of Jan 2014, use "" in the URLs in repo files.

The latest binaries are hosted here. An archive of all old releases (starting Jan 2013) is here.

The web site describing the Infinit.e REST and Widget APIs is here.

This page will contain details of all (bi-monthly) releases:

Important News, May 2015: Infinit.e is moving into a maintenance cycle as we focus new development efforts on Infinit.e's successor, Aleph2, which will be available in beta ~Q3 2015.

Here is the plan with regard to Infinit.e:

  • We recommend existing community users do not upgrade beyond the latest v0.4 release (Jan 2015). To simplify this, we are leaving the existing YUM repo ( and /infinit.e-preinstall-repo) pointed at that version. We will be rolling out bug fixes to this release.
  • We will continue to build limited new functionality (and bug fixes) to v0.5 and beyond (an increment in minor version number indicates a non-backwards compatible change) - these will be released as open source and can be obtained via different repos ( and /newest/infinit.e-preinstall-repo). (All our enterprise customers are already at v0.5+)
  • For V1 users (v0.5+) requiring/desiring the new functionality provided by Aleph2, it will be possible to use "V2" plugins within V1. These will be documented on the Aleph2 github site as they become available.

Release v0.5.1207.108 - March 2015. v0.5 upgrades a number of core technologies (Elasticsearch, Java, MonogDB, Hadoop). As noted above, v0.5+ lives in a different repository and it is recommended that v0.4- users remain at v0.4 (which will get the same bug fixes as v0.5+)
