Hi David,<br>
<br>
I can report some progress with the testing here at the Leipzig
centre. We successfully built and deployed a Fedora 6 instance from
the git repo over our Fedora 3.7.1 repo data which was exported via
the migration tool. On a first glance, all resources seem to be
accounted for (we will perform some more in-depths checks of this
soon). <br>
<br>
The only problem we encountered so far is with the migration of
external datastreams (of which we have a sizeable amount). Resources
migrated to the F6 repo which had such external datastreams in the
F3 repo do still have a reference to a corresponding child node -
but trying to access this child resource results in an internal
server error. Can you give any insight into the handling of external
datastreams in the migration process? I am aware that we might be
more of an outlier here among users, but it would be valuable
information to us whether this will be supported in any way (or
already is, and I just overlooked something). <br>
<br>
As we plan on starting to develop some initial tools to interact
with the repository, I also wanted to ask if you can guarantee that
the API will, at this point, not undergo any significant future
changes? As I remember, this is not really the focus of this version
update anyway, but I just want to make sure before we begin any
major development work.<br>
<br>
I will of course let you know of any new developments or insights as
we continue testing the F6 repository and the data migration. <br>
<br>
Best regards,<br>
Felix<br>

Hi Thomas,
<div class=""><br class="">
</div>
<div class="">I met with the tech leads to discuss your Fedora
requirements - while an OAI-PMH interface is not on the roadmap
for an initial 6.0 release, it could be added as a module soon
afterward. I’d like to get a sense of who else in the community
might have such a requirement, so I will bring it up at this
week’s tech call and post a message to the community mailing
list asking if others have a need for a OAI-PMH module at the
Fedora level. Once we determine the level of interest and
available resources we can discuss how best to implement this
feature.</div>
<div class=""><br class="">
</div>
<div class="">In the meantime, it would be great if your team
could schedule some time for testing and report back to us. The
migration tool should be able to migrate your Fedora 3.x content
to a format compatible with Fedora 6.x, and you should be able
to view and browse this data using the latest Fedora 6.x build. </div>
<div class=""><br class="">
</div>
<div class="">The migration tool can be found here: <a
href="https://github.com/fcrepo-exts/migration-utils" class=""
moz-do-not-send="true">https://github.com/fcrepo-exts/migration-utils</a>.
You’ll need to build it using Maven and Java 11.</div>
<div class=""><br class="">
</div>
<div class="">Similarly, you can build Fedora 6.x using the main
branch in this repository: <a
href="https://github.com/fcrepo/fcrepo" class=""
moz-do-not-send="true">https://github.com/fcrepo/fcrepo</a>.
Instructions are in the Readme. Or you can use the Fedora
Docker: <a href="https://github.com/fcrepo-exts/fcrepo-docker"
class="" moz-do-not-send="true">https://github.com/fcrepo-exts/fcrepo-docker</a>.</div>
<div class=""><br class="">
</div>
<div class="">Let me know if any of the instructions are unclear
or if you run into any issues. We are quickly approaching an
Alpha release so we will have packaged releases available for
testing soon as well.</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>

<div class="">Hi Thomas,<br class="">
<br class="">
Thanks very much for sharing this document - it is nice
to have a brief summary of your requirements for Fedora
6.x. I have a meeting with the technical leads on Monday
so I will share this document with them and we will
discuss how best to respond to your requirements. I’ll
get back to you with some ideas, along with instructions
on how best to test the migration tool and Fedora
development versions and report your results. The
software is quickly approaching an Alpha release so your
testing and feedback will be timely.<br class="">
<br class="">
Regards,<br class="">
<br class="">

Hello David,<br class="">
<br class="">
as promised we have discussed in CLARIN our
requirements for a repository solution. You can find
the resulting document attached. It shouldn't be very
surprising, as it just sums up the points we already
talked about in our video conference in June. Feel
free to ask if something needs clarification.<br
class="">
<br class="">
As Felix already mentioned at last week's users
meeting, we have established an interest group of
Fedora users in CLARIN.<br class="">
Its mailing list (CC'd) is meant for internal
coordination and help but also as a contact point for
you, in case of questions or a need for feedback.<br
class="">
<br class="">
I hope we can keep up the good communication between
CLARIN and the Fedora team. We are happy to help if
you need any feedback. We also should have some
capacities to test Fedora development versions or new
versions of the migration tool.<br class="">
<br class="">
Best,<br class="">
Thomas<br class="">
