Access to command arguments in transmission constraints and command verifiers

• Key: XTCE13-125
• Status: open  
• Source: Space Applications Services ( Nicolae Mihalache)
• Summary:

  Sometimes the constraints and/or verifies associated to a command may depend on the value of the arguments of the command sent. For example setting a thermostat to a certain setpoint may have a constraint which will only allow a given setpoint in a specific operational mode.
  A verifier can compare the setpoint sent as command argument with the setpoint known in the spacecraft and received as a TM parameter.

  To achieve this, arguments references should be allowed in the definition of the constraints/verifiers.

  In practice:

  • TransmissionConstraintType should extend the ArgumentMatchCriteriaType (instead of MatchCriteriaType)
  • CommandVerifierType should allow elements of type ArgumentInputAlgorithmType , ArgumentBooleanExpressionType and ArgumentComparisonType (instead of the non argument variety)

  All the Argument* types are superset of the corresponding non-argument types so by doing this change, the schema will be backward compatible.

  Note: a similar request could be argued for ParametrToSetType to allow setting a parameter to a value computed based on the user defined argument of the command. However since there is no ArgumentMathOperationType, no easy solution can be immediately seen without adding extra types.

Dynamic look up should have integer and float forms

• Key: XTCE13-109
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  Dynamic lookup is sprinkled about the text to (only?) retrieve a numeric value but perhaps there should be an integer and float form. For example in calculating a dynamic array index, would it make sense if the referred to parameter is a float? we can agree any non-numeric is a error. If it's a float or integer, the slope and intercept are doubles – suggesting a double result. Well that may produce a fractional value of an array index – that doesn't make sense. one can round or chop as one sees fits but that's not documented. in this case integer only dynamic value would make more sense – the slope and intercept would be int/long and it would be in error to ref anything but an integer parameter type. other cases may allow for either data type. [edit] Discrete lookup DOES NOT have the same issue – it's value is a float. It however does need a default. I made an issue for that.

Clarify RepeatEntry's values and what they mean

• Key: XTCE13-143
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  Firstly because repeat is optional, it seems intuitive that this is the same as repeat=0. And that intuitively means the entry repeats 0 times, which means it appears 1 time in the container entry list. Likewise a repeat=1, means the entry appears 2 times and forth. This to me makes sense but maybe it doesn't.
  The syntax right now is broad and would allow all sort of values including negative ones. It's not clear that that would be anything but an error.
  Given all that we should say something about this in the annotation at the very least. And since FixedValue is a long we could change it to positive-only or perhaps non-negative. The DiscreteLookup value's type could also be modified (we'd have to make a "PositveOnlyDiscreteLookup" or some such). The last is a DynamicLookup and that would have to be enforced outside the syntax, we could imply it by calling it "PositiveOnlyDynamicLookup" or similar.
  Finally add annotation.

Add an optional attribute to ComparisonList to make it all ORs

• Key: XTCE13-141
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  For some reason this idea flew into my funnel this morning. I was looking at the ComparisonList and noticed the annotation to it said there's an implied 'and' between all the comparisons in the list.
  I then thought: Why not add an attribute to override that to set to it all ORs? Why would that be a bad thing?
  Unable to come up with any reason that this would be a bad thing, I decided it must be a good thing and that a good thing should be an issue.
  The main reason to support the OR case is that it's simply a little easier to build out the comparisonlist than the booleanexpression. And one assumes that if it's a good thing to have an ANDed ComparisonList for convenience, that it seems like symmetrically speaking it would be a good thing to have ORed ComparisonList for conveniences as well. Basically this is just a suggested small change for the convenience purposes.

Variable string size specification enforces one of DynamicValueType or DiscreteLookupListType

• Key: XTCE13-127
• Status: open   Implementation work Blocked
• Source: Space Applications Services ( Nicolae Mihalache)
• Summary:

  In addition to the clarity issues highlighted by XTCE13-30, the current definition of StringDataEncoding has a major drawback for variable strings: the VariableStringType enforces one of DynamicValueType or DiscreteLookupListType.

  However the size of the string can be very well determined by the other two methods LeadingSize or TerminationChar. Usage of LeadingSize/TerminationChar in combination with the enforced DynamicValueType/DiscreteLookupListType does not make sense when the string fills completely the allocated buffer and so the size of the string determines the size of the buffer.

  In my opinion having a variable size buffer with a variable string inside that buffer is much less common (never heard of it in fact) than having a fixed size buffer with a variable string inside or a variable string with no buffer (the buffer is the string).

  Suggest to make the DynamicValueType/DiscreteLookupListType optional.

A value of inside "inverts" these bands: -green -watch -warning -distress -critical severe +critical +distress +warning +watch. The most common form used is "outside" and is the default."

  The key problem is the term "inverts" is not really defined and so the entire explanation is overly general.

FixedValueEntry, maybe it's not as good as it could be

• Key: XTCE13-137
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  FixedValueEntry has a hard coded hexBinary value that's supposed to be in "spacecraft order". There's a now optional name in 1.2.

  ITOS and ASIST capture the same info slightly differently. The value is in human-readable form, (e.g "5331" or whatever it is that you can read and understand). But Bit/Byte order are provided as modifiers to the field/entry definition so that the software will do the right thing and encode it properly for the final destination on the spacecraft. ITOS/ASIST require the name and other associated the meta data for these fields.

  So there's similarities overall between them but the encoding aspect is the key difference.

  The upsides to their approach are (there may be more):

  • when you see the definition, it makes some sense to you
  • the software takes care of the encoding and in a way it is then documented as to what is the both the value is and how it's going to be encoded for the final destination.

  The downsides are (could be more):

  • well something will have to be done to see the final bit values ...
  • there's more to write out to build the definition

  Is there a case to be made to change, or modify the existing fixedvalueentry? What would the approach be?

  1) maintain pure backwards compatibility: add a second variation "uservalueentry" that supplies it as described above and includes a local bit/byteorder
  2) modify fixedavalueentry itself and keep a kind of conceptual compatibility...

  What do you think?

FromBinaryTransformAlgorithm/ToBinaryTransformAlgorithm should be allowed for all data encodings

  Currently the FromBinaryTransformAlgorithm/ToBinaryTransformAlgorithm are allowed only for BinaryDataEncodingType with the comment "Used to convert binary data from an application data type to binary data".

  For example a FromBinaryTransformAlgorithm attached to a IntegerDataEncoding can extract a varint like the ones used in protobuf (https://developers.google.com/protocol-buffers/docs/encoding#varints).

  Similarly a ToBinaryTransformAlgorithm attached to a FloatDataEncoding can be used to encode a floating point number in an exotic format; for example bfloat16 is commonly used in AI chips (https://en.wikipedia.org/wiki/Bfloat16_floating-point_format)

Is rangeForm specialization needed for Change and Multi band alarms?

• Key: XTCE13-74
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  RangeForm now appears in Static, Change and the multi band. It's not clear these all make sense to me.

  In the static ranges – having the red be the most severe inner band and green "good" on the outside does make sense although I get the impression the use cases are less in number than the standard way folks think of limits. (you're going too fast! not – you're not going fast enough!)

  In the change alarm, which I think of mainly as deltas – again intuitively checking for big changes make sense. Unwanted big jumps are intuitive. But unwanted little jumps? That is big jumps are good? Is there a real use case – perhaps we can jam it into the annotation.

  Finally for the multirange alarm. The rangeForm is at each band. I suspect but don't know that this was to change the range set meaning...
  Intuitively "inside" would be something like this: [min, max] – where x is between them is "ok" ...

  And "outside" would be (-inf, min] and [max, inf) ... that is ranges point 'away'...

  But maybe not – who knows!? Given that though the default is "outside" when perhaps most would want it to be "inside" etc...

  I just wonder if we have done this correctly or its slipped through and is overly general because we inherited the various types, etc...

String Encoding Length descriptions needs further clean up

• Key: XTCE13-30
• Status: open  
• Source: NASA ( Mr. James Kevin Rice)
• Summary:

  The current schema improves upon XTCE 1.1 but still has issues. Firstly it lacks overall clarity and simple syntax. Second it appears to give 2 ways to describe an overall "string box" and dynamic part which may be confusing to some (we should favor one over the other). See for example Fixed plus one of the TerminatingChar or LeadingSize, or Variable/DynamicValue and maxSizeInBits. Also maxSizeInBits is required and this may be a problem in some scenarios. Finally the choice of syntactic element does make it possible to say that variable length has a dynamic look up terminatingChar and LeadingSize.

  The overall use cases of support are:

  • fixed string
  • fixed box, variable string
  • variable string but overall max size (simlar to above)
  • variable string unlimited

  Here's a longer write up:

  1) Fixed string, like as in literally:

  StringDataEncoding/SizeInBits/Fixed/FixedValue

  2) Fixed string BOX but variable inside that...

  StringDataEncoding/SizeInBits/Fixed/FixedValue AND one of Fixed/LeadingSize or Fixed/TerminatingChar

  3) Fixed string BOX but variable inside that... yeah we can say this two ways then:

  StringDataEncoding/Variable/@maxSizeInBits=sizeOf(StringBox) AND one of DynamicValue or DiscreteValue to look up the length from it, and then optionally either LeadingSize or TerminationChar or both even too

  This one is terribly confusing...

  4) Variable and Max size

  StringDataEncoding/Variable/Dynamic|Discrete plus required maxSizeInBits and then optionally either LeadingSize or TerminationChar too

  5) Variable but no max size stated in source material

  StringDataEncoding/Variable/Dynamic|Discrete set maxSizeInBits to ginormous and probably just ignore and then optionally either LeadingSize or TerminationChar too

  So #1 and #2 make sense but are a tad unwieldy syntax wise... well we are probably a little stuck there in regard to "backwards compatibility". This is probably the most used, these two.

  I think #4 makes sense – although mixing in the leading size or termination char seems either just plain confusing or weird...

  #5 is unfortunate but making @maxSizeinBits optional seems quick fix OR the workaround isn't necessarily bad.

  The "let's set everything" #3 isn't great but could be factored away in documentation

reference to aggregate members and arrays

• Key: XTCE13-126
• Status: open  
• Source: Space Applications Services ( Nicolae Mihalache)
• Summary:

  The XTCE spec is not very clear on how the aggregate members can be referenced (for example in match criterias). The doc of AggregateParameterType reads:
  "Each member may be addressed by the dot syntax similar to C such as P.voltage if P is the referring parameter and voltage is of a member of P’s aggregate type. See MemberType, MemberListType, DataEncodingType, NameReferenceType, and AggregateDataType".

  However the definition of "NameReferenceType" is silent about aggregates and the "." (dot) character is not allowed to be used in a reference (except in the "./" where it denotes "current space system). The reference suggested above "P.voltage" is invalid.

  In some examples over the internet references to aggregate members are found using standard "/" separator. However this is problematic because a reference like "/A/B/C" is ambiguous, could translate into:
  A (space system)/B(space system)/C(parameter name)
  or
  A(space system)/B(parameter name)/C(aggregate member name)

  Suggest to allow dot notation to reference aggregate members. Similarly allow "[idx]" to reference array indices.

  For example a reference "/A/B.C[3]" can be unambiguously understood as:
  A(space system)/B(parameter name).C(aggregate member name of type array) [3] (index in the C array)

  Perhaps NameReferenceType can be made less restrictive or another type can be defined and used in the ParameterRefType definition.
