Issues Descriptions

Schema appears to be missing root element

  • Status: open  
  • Source: JHU/APL ( Michael Leatherman)
  • Summary:

    The document seems to missing the dds element at the very end of the schema.

    Probably OBE, but the 1.0 version of the PDF also is missing the element. In the xsd version of the 1.0 spec, the root element is dds_ccm, which doesn't match the XML File Syntax section (page 46 of the version 1.0 PF).

    Finally, the XSD download for 1.1 is not working when I click on the link on http://www.omg.org/spec/DDS4CCM/1.1/ Only the UML document is available in the informative machine consumable documents section.

    Thanks.

Remove key_fields

  • Status: open  
  • Source: Remedy IT ( Johnny Willemsen)
  • Summary:

    We propose to remove key_fields completely from the DDS_TopicBase connector. The knowledge which fields are a key is specified in IDL using annotations and shouldn't be set again on the connector instance. This is duplicate information which could only lead to inconsistencies and possible problems. Until now we also have not seen any use case which require this information to be available as StringSeq as part of a connector instance.

Make topic_name changeable

  • Legacy Issue Number: 16603
  • Status: open  
  • Source: Remedy IT ( Johnny Willemsen)
  • Summary:

    In some systems they are receiving the topic_name after startup, at some moment they just get it and want to set it to a new value. We propose to remove topic_name, there seems to be no technical or structural reason not to allow the user to change the topic_name after the connector fragment has been initialized

proposed simple spec extension for common DDS use case

  • Legacy Issue Number: 18992
  • Status: open  
  • Source: THALES ( Virginie Watine)
  • Summary:

    In paragraph 7.2.2.1.2, a note about interface Reader says:

    << Note: This interface is the basis for a passive data reader (i.e. a component that just looks at the data as they are). It is also very useful for the reactive data getters (i.e. components that need to react to new data, whether they choose to get them in pull mode or be notified in push mode) in their initialization phase. This is the reason why all the DDS ports on the subscribing side will embed a Reader basic port.>>

    This note may let people think that it is ONLY useful in initialisation phase, which is not true. A clarification sentence would avoid that misunderstanding.
