Issues Descriptions

name, label and other similar fields should be greater than 64 chars max

  • Key: XUSP11-36
  • Status: open  
  • Source: NASA ( Mr. James Kevin Rice)
  • Summary:

    64 char limited names seemed reasonable however many years ago and in general this is true, nonetheless in our various GSFC conversion efforts we have consistently found a few parameter names that are longer. Usually this is in reference to a "flattening" process from a long complex type style definition to a single long dotted and array subscripted name. The result in a few cases of an overall database is greater than 64.
    Most systems also seem to provide a way to make a shorter global "alias" so while holding these long named items in some internal table.

XUSP should allow nesting of SpaceSystems inside SpaceSystems

  • Key: XUSP11-42
  • Status: open  
  • Source: Kratos RT Logic, Inc. ( Mr. Justin Boss)
  • Summary:

    Nesting should be allowed.

    Need to determine if nesting should be limited/constrained to prevent unlimited nesting.

  • Updated: Thu, 13 Jun 2024 16:45 GMT


XUSP should not prevent use of Critical alarm severity as it is recommended by XTCE

  • Key: XUSP11-40
  • Status: open  
  • Source: Kratos RT Logic, Inc. ( Mr. Justin Boss)
  • Summary:

    XTCE mentions:

    Typical implementations color the "normal" level as green, "warning" level as yellow, and "critical" level as red.

    As such, XUSP should allow the use of critical.

Deprecate usage of severe alarm level

  • Status: open  
  • Source: Kratos RT Logic, Inc. ( Mr. Justin Boss)
  • Summary:

    In alignment with the XTCE specification and Space DTF standardization, the severe alarm level should not be used. The substitute alarm level should be critical going forward.

XUSP 1.1 should not include AlarmMultiRanges

  • Key: XUSP11-6
  • Status: open  
  • Source: Northrop Grumman ( Mr. Joseph Vlietstra)
  • Summary:

    AlarmMultiRanges feature was added in XTCE 1.2. This feature should not be included in the XUSP 1.1 update since is too complex for the target alarm model.

ParameterToSet/Derviation is set to abstract and should not be

  • Key: XUSP11-11
  • Status: open  
  • Source: NASA ( Mr. James Kevin Rice)
  • Summary:

    ParameterToSet/Derivation is a MathOperationType which is abstract. Which means you can make an instance of it.

    A simple fix is to make a DerivationType extending MathOperationType.

Enhance support for VCID to not depend on AncillaryData

  • Key: XUSP11-16
  • Status: open  
  • Source: Kratos RT Logic, Inc. ( Mr. Justin Boss)
  • Summary:

    Since the VCID is telemetered and is a standard CCSDS construct, suggest that supporting VCID be promoted to being supported first-class instead of via the AncillaryData construct.

    Also, SCID and other transfer frame constructs should be similarly supported.

XUSP 1.1 should not include rangeForm="inside"

  • Key: XUSP11-7
  • Status: open  
  • Source: Northrop Grumman ( Mr. Joseph Vlietstra)
  • Summary:

    rangeForm attribute was added in XTCE 1.2. This attribute allows severity level between alarm ranges to be reversed (that is, rangeForm="inside" causes the more severe alarm ranges to inside of less severe alarm ranges). The rangeForm="inside" option not be included in the XUSP 1.1 update since is too complex for the target alarm model.

Eliminate extraneous whitespace in XUSP CSV file

  • Status: open  
  • Source: Northrop Grumman ( Mr. Joseph Vlietstra)
  • Summary:

    The XUSProfileRules.csv file contains extraneous spaces between commas. The spacing between commas is inconsistent it's mostly “, ,” but frequently “,,”. These spaces cause non-empty entries when the CSV file is imported into Excel.

The label attribute of a ValueEnumerationType should be limited in length

  • Key: XUSP11-4
  • Status: open  
  • Source: Peraton ( Brad Kizzort)
  • Summary:

    Most names and fields in XUSP have added limits to the string length. There is no limit on the label size. I recommend that it match the mnemonic length of 64 characters.

The following schema-type have a funny character encodings in annotation, create problems

  • Key: XUSP11-12
  • Status: open  
  • Source: NASA ( Mr. James Kevin Rice)
  • Summary:

    The following 4 schema-types have funny character encodings for quotes or similar in a few lines of annotation, probably from Word editing.

    BinaryArgumentType
    BinaryDataType
    BinaryParametertype
    ServiceRefType

    The errors are around "" items like "dangling reference" and some of the path related items.

    approx. lines 20, 22, 26 and 58 per each file.

    This makes some things complain – maybe compilers, Javadoc other tools.

    The quick fix is to simply edit the schema and fix them, then motor on your way.
