Title: What does the version parameter in MCWS do?
Post by: mattkhan on January 01, 2018, 07:20:08 am

Some MCWS endpoints (e.g. Browse/Children, Library/Values) accept a parameter named version which is described as

Code: [Select]

Version: The version of the data used for results (2 is the newest version). (default: 1)

I have tried 1 and 2 on a few calls and I can see that using Version=2 means the output from Browse/Children gains an attribute Type="2" , i.e.

Version = 1

Code: [Select]

<Response Status="OK">
<Item Name="(Multiple Artists)">1044</Item>

Version = 2

Code: [Select]

<Response Status="OK">
<Item Name="(Multiple Artists)" Type="2">1044</Item>

What does this mean? The output doesn't seem to vary in any other way.

It may mean the database version.  MC21 and earlier used one version.  MC22 and later used another.

If the latest version is not the default, it's usually an experiment to expose some incompatible data or something like that. I'm not quite sure about the exact call in question however.

OK thanks, I guess I can just ignore it then (and use the default).
