<p class="MsoNormal"><span style="font-size:11.0pt">Dear All,<br>
<br>
<br>
Thanks again for the insightful Zoom meeting. This helped me a lot in developing a new version of CollEc. And thank you Thomas for allowing me to advance this interesting project.<br>
<br>
After spending much of this week on developing the new CollEc, it is now quasi done.
<br>
<br>
The user interface is similar to that of RePEc Visual. Users interactively navigate through the app and are presented with CollEc data through graphical output. A documentation contains variable definitions, details on the technical implementation etc. I wrote
the documentation so that someone who never heard of graph theory understands what CollEc displays.<br>
<br>
The SQL implementation and the code generating the CollEc data from RePEc Author Service inputs are also almost ready for upload.<br>
<br>
What I am still having some difficulties with is deploying apps through Docker containers. I am going to take a course on Docker this weekend and expect to deploy a test app some time next week.<br>
<br>
CollEc's server does not really have any vacant CPU capacity to test the web application. I therefore suggest to upload the test application to another server where everyone on this list can access it with a password. After this testing phase it can then be
officially released on the actual server.<br>
<br>
Feel free to share your thoughts on this.<br>
<br>
Have a nice weekend.<br>
<br>
<br>
Kind regards,<br>
Christian<br>

As far a I understand we need a binary network. Otherwise can can easily<br>
be an a situation where we say that the shortest path between A and C<br>
is through B, even though A and C have written a paper together. <br>

It would be many many times faster than what I do now.<br>

Yes, 19:30 my time. <br>
