[topbraid-users] Basic and Form-based authentication

[Marcus Jowsey]

Quick question.

Is it possible in Tomcat to enable both Form-based and Basic authentication 
for TopBraid EDG or must it be one or the other?

cheers,
Marcus

Re: [topbraid-users] Re: Deleting a user from EDG server, and removing all user triple references in governance

[TopQuadrant Support]

Hi Simon,

When EDG is configured to use LDAP, EDG delegates the user authentication
to the servlet container (Tomcat), which further delegates it to LDAP.  The
case-insensitivity you describe is an unfortunate aspect of using LDAP,
particularly Active Directory.  Lately, more customers are using SSO (SAML)
for authentication, which gets user information via Assertions from an
Identity Provider (IDP), and does not rely on whatever the user types in.

It seems you have found the way to resolve the "duplicate" user via edits
to  and change history graphs (.tch), however, as you
correctly surmised, this way should only be used with great care.  Removing
a user is not a common operation, so we don't have a documented procedure.
It also has cascading effects when the user to be removed has performed
actions on graphs.  You would have to edit the change history for every
graph the user has touched.  We typically use the SPARQL endpoint on the
rare occasions where we have to do this internally.

Please let us know if you require further assistance.

Thanks,
-Ken

Here’s the 7.1 online documentation Scripting with JavaScript and ADS:

https://www.topquadrant.com/doc/7.1/scripting/index.html 


which has code snippets you can try.

Re: [topbraid-users] Question on SPARQL Web Pages File(.swp)

[deviredd...@gmail.com]

Hi Holger,

Yes, we have few SPARQL Web Pages File(.swp) files and Many RDF/SWP 
files(.ui.ttlx). 

I understand that as of 7.1 SPARQLMotion servlet/feature has been removed 
and also that at some stage SPARQL Web Pages File(.swp) feature will be 
removed. Any idea on what will happen to RDF/SWP files(.ui.ttlx) in near 
future?

A basic question on scripting with ADS/JavaScript, can this be used as an 
alternate to all SPARQL Web Pages Files(.swp), RDF/SWP files(.ui.ttlx) and 
SPARQLMotion scripts(.sms.ttl)? Could you please share a simple 
example/document on how to get started with ADS/JavaScript? 

Thanks,
Sanjeev

To: 'Felix Sasaki' via TopBraid Suite Users 
Subject: Re: [topbraid-users] Question on SPARQL Web Pages File(.swp)

Hi,

Irene explained the approach and rationale in a response to this forum at 7.1 
Beta release:

1. As stated in the release notes, running EDG within TBC was never exactly the 
same as running EDG server. Supporting this mode complicated certain aspects of 
our codebase and still was not 100% the same. We decided to simplify the code 
in order to provide more reliable, maintainable and better optimized software 
for our customers. For example, EDG Studio does not have any Eclipse in it and 
it does not use Jetty.

At the same time, for users who are only interested in TBC having EDG in TBC 
delivered no value and, instead, created some inconveniences for them e.g., 
slow start up due to the need to initialize the server.

So, after careful consideration we decided to separate the two tools. It is a 
change and changes can take getting used to. However, we believe it is a change 
for the better and we do not intend it to leave any current or prospective 
customers in the dark. Functionally, the same options exists with 7.1 and we 
are actually considering what else we could offer to the community.


Ø I fully support these changes and see all the benefits

2. Some users were using it in order to explore and evaluate EDG prior to the 
purchase which, as you say, requires a more significant commitment than TBC.

This need could be addressed by requesting an evaluation server from 
TopQuadrant. It is true that this would be for a limited period e.g., a month 
or two. However, this approach is not unique to TQ. It is pretty much industry 
standard.


  *   Exchanging existing functionality for an evaluation variant is I think 
not fair (maybe legally not even ok)
  *   We made demos to clients involving excel imports, You once us advised not 
to use TBC for that but EDG because those modules were actually developed 
further and supported. When upgrading, these demos would not work anymore.


Beyond the beta, there is no technical reason why we could not license 
TopBraid EDG Studio to users who do not have EDG. We have not made this option 
available at the time of 7.1 beta because we are still considering what would 
work best for our user community and for TQ. We also are looking at other 
alternatives that may be better aligned with our move towards SaaS e.g., 
offering a hosted “Community Edition” of EDG that would have more limited 
features.


  *   I am looking forward to a better solution like

 *   Some “EDG personal edition”, local or saas, or
 *   Some Community saas version having the same functionality, or
 *   Having a good deal for EDG, I see no explicit pricing for EDG at: 
https://www.topquadrant.com/products/purchase/


In the meantime, we appreciate users input on what they would prefer and 
why.


  *   Hereby … greetings, Michel

WRT Irene's request for alternatives, preferences and suggestions going 
forward, best to not think that creating a parallel EDG codebase for Composer 
again is a viable option. If some of the rationale for your needs involve 
projects/contracts that are not public knowledge, probably best relay those 
ideas by contacting TQ staff with whom you are already familiar directly to 
have a more private conversation.

Cheers,
David

The bummer part of this product architecture change is now it is impossible to 
utilize the excellent model driven application capabilities that have always 
been a part of TBC without buying EDG server.  I like the EDG environment but I 
dont necessarily need the data governance capabilities (e.g  the ontologies).  
Having a TBL-like version (personal and/or server) would suit a lot of my needs.
