Schema (xsd) for CVT Tag File

[deepforge]

Where can I file the .xsd file for tag files loaded to/stored from the Current Values Table (CVT) library?

I have a pressing situation.  I am the software lead for a machine control project that relies heavily on customer configurability and tag management.  I proposed an architecture that included use of CVT, CCC and the TCE to manage configurations; only to find out the update to TCE v2.x broke XML compatibility with CVT.  The project at NI to update the CVT to remedy this doesn't seem to be making much progress, so I have to fashion a workaround to meet my timeline.  My plan is to use an open source or COTS XML tool to manage configuration instead of the TCE.  However, I need a copy of the xsd to make a solution that's consumable for the customer.

Where do I find this?

Side note:  I've noticed similar questions raised for other LabVIEW components.  I would suggest posting standards and schemas in a document area of decible.ni.com.

Hello deepforge,

Please take a look to the nect information:

I've read that article mutliple times.  There's no reference to the XML schema.  Was there a specific XSD file you saw mentioned?

deepforge,

Have you already read the next information? https://www.ni.com/docs/en-US/bundle/labview/page/converting-data-to-and-from-xml.html

At the end it tells the following:

LabVIEW XML Schema

LabVIEW converts data to an established XML schema. Currently, you cannot create customized schemas, and you cannot control how LabVIEW tags each piece of data. Also, you cannot convert entire VIs or functions to XML.

The predefined XML schema that LabVIEW uses is LVXMLSchema.xsd located in the labview\vi.lib\Utility directory. You can open the file in a text editor to read the schema.

Oh, I see.  You're saying that the CVT uses the common LabVIEW XML schema.  Okay.
