Why Copy-Pasting your Schemas Is Not a Good Idea

Image
By
I just noticed something concerning -- I copy-pasted a Schema in Tridion 2011 SP1 HR1 and I noticed the UUID namespace of it did not change. In fact I ended up with two different Schemas having the exact same namespace.

So far, I have not found a case where that breaks, but it not look good to me (i.e. that UUID seems like it was put in place for a reason).

For me, the root nodes of the two Schemas are not the same, but some of the fields are. I believe there can be a clash there.

Still thinking for a use case where that breaks...

Will be a PITA if you are making use of XSLT templating :) for Compound it's not going to bother you :)

This is a good example of a default value setting expectations.
In this case, the wrong expectations. The target namespace does not have to be unique and it shouldn't be changed automatically when you make a copy.

My guess is that the default value is unique mostly because we didn't think people would want it to be a tridion.com URL. And since you need the target namespace to have a valid XSD, it must have a value from the very beginning. You can't wait for the user to enter a value.

Speaking of the target namespace: it really should have been added long ago as a field on the General tab.

Running sp_updatestats on AWS RDS database

By
Part of the maintenance tasks that I perform on a MSSQL Content Manager database is to run stored procedure sp_updatestats . exec sp_updatestats However, that is not supported on an AWS RDS instance. The error message below indicates that only the sa  account can perform this: Msg 15247 , Level 16 , State 1 , Procedure sp_updatestats, Line 15 [Batch Start Line 0 ] User does not have permission to perform this action. Instead there are several posts that suggest using UPDATE STATISTICS instead: https://dba.stackexchange.com/questions/145982/sp-updatestats-vs-update-statistics I stumbled upon the following post from 2008 (!!!), https://social.msdn.microsoft.com/Forums/sqlserver/en-US/186e3db0-fe37-4c31-b017-8e7c24d19697/spupdatestats-fails-to-run-with-permission-error-under-dbopriveleged-user , which describes a way to wrap the call to sp_updatestats and execute it under a different user: create procedure dbo.sp_updstats with execute as 'dbo' as...

REL Standard Tag Library

By
The RSTL is a library of REL tags providing standard functionality such as iterating collections, conditionals, imports, assignments, XML XSLT transformations, formatting dates, etc. RSTL distributable is available on my Google Code page under  REL Standard Tag Library . Always use the latest JAR . This post describes each RSTL tag in the library explaining its functionality, attributes and providing examples. For understanding the way expressions are evaluated, please read my post about the  Expression Language used by REL Standard Tag Library . <c:choose> / <c:when> / <c:otherwise> Syntax:     <c:choose>         <c:when test="expr1">             Do something         </c:when>         <c:when test="expr2">             Do something else         </c:when...

Publish Binaries to Mapped Structure Groups

By Unknown
Today's TBB of the Week comes from the high demand in the field to publish binary assets to different mapped Structure Groups. By default SDL Tridion offers two ways of publishing binaries: All binaries publish to a folder defined in your Publication properties; All binaries rendered by a given template publish to a folder corresponding to a given Structure Group; In my view, both cases are terrible, over-simplified and not representing a real use-case. Nobody in the field wants all binaries in one folder and nobody separates binary locations by template. Instead, everybody wants a mapping mechanism that takes a binary and publishes it to a given folder, defined by a Structure Group, and this mapping is done using some kind of metadata. More often than not, the metadata is the TCM Folder location of the Multimedia Component. I have seen this implemented numerous times. So the solution to publish binaries to a given location implies finding a mapping from a TCM Folder to a...
