Subject Re: [DISCUSS] Commons RDF to join the Apache Incubator

Hi all,

at first sorry for the delay. I've been on vacation the last 10 days with
no access to my emails.

Short answer: The Apache Commons community is fine with this.

Long answer: There has been some confusion (and misunderstanding?) about
the way the Apache Commons project works. The Commons RDF community wanted
to use either github or a separate mailing list for shaping out the initial
API. The first in our opinion doesn't work since Apache projects have to
use Apache infrastructure. The latter wasn't possible since we don't what
to create sub communities inside commons [1]. This is a lesson learned from
Jakarta (note that I've not been around by the time Jakarta shout down, so
I'm just writing down, what I've learned from others). This eventually led
to the suggestion to go though the incubator. [2]

We like to underline, that we have no experience with the RDF
specification. From a technical point of view we can help to develop the
proposed API (according to our design guide lines [3]). But we need the
people the the RDF space to review contributions from a semantic PoV. So
this should not end up like developing the RDF library at the incubator and
then hand it of for maintenance to the Commons community. I think all
people involved here have pointed out, that they are willing to work on the
project even after it's initial release. Note, that we have recently
granted write access to all ASF committers [4]. So if Commons RDF
eventually moves to Apache Commons, anybody from the Jena/Sesame/Clerezza
projects may join the development.

In the case of Commons RDF going TLP we would like to ask the project to
choose a different name to avoid confusion. But I think this has already
been discussed in this thread.
