Subject Re: [VOTE] Accept Unomi into the Apache Incubator
Date Wed, 23 Sep 2015 13:03:15 GMT
Thanks Raul for the clarification. JB used the original email as the base for the text proposal
but we will use the Wiki text for the official incubation text, no worries.

>> widely distributed cloud architectures. Geode pools memory (along with CPU,
>> network and optionally local disk) across multiple processes to manage
>> application objects and behavior. It uses dynamic replication and data

>> == Known Risks ==
>> Development has been sponsored mostly by a single company (or its

>> The tools and development practices in place for the Jahia Marketing
>> Factory product are compatible with the ASF infrastructure and thus we do
>> not anticipate any on-boarding pains. Migration from the current GitHub
>> repository is also expected to be straightforward.
>> == Orphaned products ==
>> Jahia is fully committed to Jahia Marketing Factory and the product will
>> continue to be based on the Unomi project. Moreover, Jahia has a vested
>> interest in making Unomi succeed by driving its close integration with
>> sister ASF projects. We expect this to further reduces the risk of

>> Marketing Factory product, and at the time of this proposal both the
>> commercial offering server and Unomi source code are 100% the same. It is
>> expected over time that Jahia will develop additional modules on top of
>> Unomi that may not be open sourced but other companies may of course do the
>> same thing.
>> == Inexperience with Open Source ==
>> Jahia has been developing and using open source software since its
>> inception in 2001. Jahias CTO and Chief Software Architects are Apache
>> Committers and other employees have contributed to various ASF projects
>> over the years. Additionally, several ASF veterans agreed to mentor the
>> project and are listed in this proposal. The project will rely on their
>> guidance and collective wisdom to quickly transition the entire team of
>> initial committers towards practicing the Apache Way.
>> == Homogeneous Developers ==
>> While most of the initial committers are employed by Jahia, we have
>> already seen a healthy level of interest from our existing customers and
>> partners. We intend to convert that interest directly into participation
>> and will be investing in activities to recruit additional committers from
>> other companies.
>> == Reliance on Salaried Developers ==
>> Most of the contributors are paid to work in web marketing/web content
>> management space. While they might wander from their current employers,
>> they are unlikely to venture far from their core expertises and thus will
>> continue to be engaged with the project regardless of their current
>> employers.
>> == Relationships with Other Apache Products ==
>> As mentioned in the Alignment section, Unomi may consider various degrees
>> of integration and code exchange with Apache Karaf, Apache Mahout, Apache
>> Pistachio (incubating), and many others. We look forward to collaborating

>> umbrella.
