Resource Manager - Adding entities via web interface fails

Tuesday, April 03, 2012 2:14 PM

Hi everybody,

I'm back with more errors. After creating the custom data model, I've attempted to add an entity via the Resource Manager. First I tried a File resource (Zentity.Core) and that failed (the errors are identical, so I will only post one for brevity), then I tried creating a custom entity (MyModel.Model). It took a very long time (10+ minutes) to even get this error. Slow processing?Error is below:

Repro steps:

Start Zentity Resource Manager (after adding custom model)
Log in as Administrator (I used the built-in admin account, no Windows authentication)
Try to add an entity (fill in Title, Description and Uri)
Wait....
Error (see above)

I really need this to work, it would be great to find out what's behind it and why Zentity generally dislikes models other than ScholarlyWorks.

Cheers,

Wiz, please let us know on the status of this issue. Are you still facing this issue? I tested at my end with a custom model and is working fine.

Hi Kalnemi, yes I am still having the issue. Could you please paste here how you have created that custom model? Maybe the problem appears only when importing from RDFS.

Cheers,

WizMan

Hi Wiz,

I did the test on USPresident and TestScholarlyWorks (a modification of ScholarlySample rdf that comes with installation). Both were added using the RDFs and powershell script. I able to add resources of the both type using ZRM.
