Summary0002842: 5.2.4 BrowseName: Case Sensitivity of BrowseName is Required?
Description

CMPWG 9/4/2014:

The very last sentence in section 5.2.4 says:

"The string-part of the BrowseName is case sensitive."

Elsewhere in the spec case-sensitivity is described for NodeId, but not for BrowseName. Does this sentence mean that ALL Servers must reject TranslateBrowsePath... requests when case does not match even if the server is not case-sensitive?

TagsNo tags attached.

Should we clarify the spec to treat case sensitivity for BrowsePath the same as we do for NodeIds in Mantis 1406?

"Defined that string-part of BrowseName shall be case sensitive and the string-part of a NodeId shall be assumed to be case sensitive but servers can make aliases supporting case-insensitive string-parts of NodeIds."

My assumption is this is only relevant for TranslateBrowsePath... and I would suggest that we would add text there stating that this service might return nodes that cannot be found by browse.
1.) We have no concept of aliases in BrowseNames
2.) In FDI we have non-browsable nodes and they would need to be accessible with this service. You could argue at the moment this is not allowed by OPC UA spec (I never thought about that before).

Added Text to BrowseName:
That is, Clients shall consider them case sensitive. Servers are allowed to handle BrowseNames passed in Service requests as case insensitive. Examples are the TranslateBrowsePathsToNodeIds Service or Event filter.

Agreed to clarification edited in the ua call.
