Hi, have a good day.

I'm doing some practices with windchill and  trying to understand how it works. Now I have a doubt.

What is the difference between  these two prefixes in objects ID

VR:wt.part.WTPart & OR:wt.part.WTPart

Thank You for your time.

<class>:<key> : string representation of an ObjectIdentifier.
OR:<class>:<key> : string representation of an ObjectReference.
VR:<class>:<key> : string representation of an VersionReference.

Snippets:

/* ObjectIdentifier string to WTPart */

ObjectIdentifier oid = ObjectIdentifier.newObjectIdentifier("wt.part.WTPart:20154");

WTPart part = (WTPart) PersistenceHelper.manager.refresh(oid);


/* ObjectReference / VersionReference string to WTPart */

ReferenceFactory rf = new ReferenceFactory();

WTReference ref = (WTReference) rf.getReference("OR:wt.part.WTPart:20154");

WTPartpart = (WTPart) ref.getObject();


ReferenceFactory rf = new ReferenceFactory();

WTReference ref = (WTReference) rf.getReference("VR:wt.part.WTPart:20153");

WTPart part = (WTPart) ref.getObject();

    Might be more info than you want, but for objects that are versioned (like WTParts), there are two objects created - the "Master" and the first Version.  Certain operations apply to the Master (e.g. Rename).  Attributes are applicable to either the Master or each Version (if each Version, they are "Instance based attributes" or IBAs).

    The URL is either for the Master object or a specific Version.
