[Dev] SMC Browser - update

[Oddrun Ohren]

Hi Matej,

Thanks for the new version!  As I have said before, I find your tool highly informative and helpful. It also visualizes very clearly some of the problems with CR as it is today, notably the many duplicate or near-duplicate components and elements. I also think that a controlled vocabulary for domains (of profiles) could make the profile-domains graph really helpful. Introducing a similar attribute for components (something like "described object" with an accompanying vocabulary/ontology) would make the foundation for a corresponding graph component-described object. That way, it would be easy to detect components which describe persons, for example, without having to rely on them being called "person-" something or other.



With further development, I think CMD Browser could become a CMD analysis and management tool. For this we would need facilities like

*         profile/component comparison (e.g. compare selected components in terms of overlap, inclusion, etc.  Relations to investigate must of course be clearly defined), with textual/tabular report

*         detect profiles/components/elements which are similar to a given component ("similar" defined partly by user, e.g. "includes >= 80 % of the same DCs")

*         ...and more. We would have to think more about this...



Even further down the line, perhaps a graphical modeling tool could evolve, allowing the metadata modeler to create/update profiles by dragging/dropping components, elements and data categories on to a graphical canvas.



Back to the current version: Using Chrome, I have a little trouble with graphs extending past the window borders. The scroll bars don't seem to cover the whole canvas. Any attempt to manually move the nodes is undone by the automatic layout mechanism. I tried freeze, but then I still can't get hold of the nodes outside the accessible part of the canvas. Anything else I could have done, apart from using the layout parameters in the top bar?).



Best regards,
Oddrun

Dear all,



there is an updated version of the SMC Browser available (under the old

address):



http://clarin.aac.ac.at/smc-browser/





Besides freshly fetched data, there are also some new features and fixes:



* profiles that are still private, but already have instance data exposed have been also processed, making it altogether 154 available profiles.



* introduced new type of nodes: *profile-groups*

   based on profile metadata: creatorName, groupName and domainName

   virtual nodes (for each distinct value of the three fields) are being generated and linked with appropriate profiles.

so now it is easy to see which profiles are grouped together or who created which profile (i hope the authors dont mind being dots in a graph - aren't we all just tiny dots in a giant graph after all ;) )



  especially there is a dedicated group for profiles, that are not

  public yet: "unknown-profile"

  you can inspect directly under:

http://clarin.aac.ac.at/smc-browser?graph=/smc/data/smc-graph-groups-profiles-datcats-rr.js&depth-before=1&depth-after=1&link-distance=120&charge=594&friction=75&node-size=4&labels=show&curve=straight&layout=horizontal-tree&selected=profile_group_unknown_profile&





* it is now possible to select different graphs (param: graph)

   currently 4 different ones are available:

   1. the basic one (profiles -> components -> elements -> datcats)

   2. additionally rendering the new profile-groups and relations between data categories (from Relation registry)

   3. just rendering profiles and data categories (with direct links between those, skipping all components and elements

   4. as 3. but again with profiles-groups and relations



3. and 4. are good to better inspect profile-proximity



* all data categories should be resolved now.

   (in the previous version many datcats had no definitions fetched from

isocat)

   I also encountered quite a few concept-links with leading space, and other inconsistencies. I will soon provide a list of the affected CMD-elements, perhaps, we can clean this up in the Component registry...



* the (statically generated) dataset (especially the statistics) are getting quite big, so it may take a bit until everything is loaded.

a more dynamic version sending around smaller chunks of data is scheduled. meanwhile I have to ask you for patience.



I hope you like it.

looking forward to feedback.





best,

matej
