Issues Descriptions

Length of subsystem parameter string types

  • Key: OARIS-76
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The length of the subsystem parameter string types is contrained to a maximum of 32 characters. This is not long enough to accomodate a hierarchical naming scheme with (potentially long and) meaningful names at each level.
    This issue only impacts the IDL for the DDS PSM. The specification at PIM level does not specify a maximum length.

Inconsistent mechanisms for determining subsystem state across use cases

  • Key: OARIS-75
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    Across several of the subsystem control, sensor control and sensor tracking use cases the mechanism for determing subsystem state are inconsistent and some cases do not allow for this without modifying the subsystem's state. CMS functionality will in many cases need to determing current state of the subsystem (without modification) - e.g. to present a control window to an operator.

    (extract from Nick Davies email - Thales)
    Looking at some of the sensor management and CMS use-cases, there seems to be 3 patterns used to obtain the state of the subsystems amongst the interfaces. Those patterns are essentially:

    • Modify/Response
      The CMS issues a modification request to the subsystem. The subsystem will then call the CMS back with the new state (or old if unsuccessful); the state published will only include the attributes that pertain to the original modify request. The callback is mapped to the original request through a request ID attribute that is present in both request and response.
    • Request/Response
      The CMS issues a report request to the subsystem. The subsystem will then call the CMS back with the current state; the state published will only include the attributes that pertain to the original report request. The callback is mapped to the original request through a request ID attribute that is present in both request and response.
    • Notification
      The subsystem notifies CMS of the current state in an unsolicited fashion, either periodically or on state change

    For each of the use-cases in detail:

    • ‘Manage Subsystem Parameters’ use-case uses both request/response and modify/response – there is no callback interface for retrieving data.
    • ‘Manage Frequency Usage’ use-case uses modify/response and Notification pattern. There is a ‘report_frequencies_state()’ method for notifying frequency state either periodically or on change, and also a ‘transmission_frequency_state’ method that reports the changed frequencies in response to a specific request. For transmission mode, however, there is only the modify/response mechanism – there is no way of discovering the transmission mode without setting a value.
    • ‘Control Battle Override’ use-case uses the modify/response mechanism – there is no way of discovering the battle override state without setting a value
    • ‘Control Emissions’ use-case uses the modify/response mechanism – there is no way of discovering the emissions state without setting a value first
    • ‘Manage Technical State’ use-case uses all three patterns – there is a modify/response interface, a request/response interface and a pure notify interface
    • ‘Manage Operational Mode’ use-case uses the modify/response mechanism and the request/response mechanism. However, the interface specifies that the response interface can also be used for ‘spontaneous’ mode change, where a request_id of 0 will be specified.
    • ‘Manage Tracking Zones’ use-case uses the modify/response mechanism
    • ‘Manage Transmission Sectors’ use-case uses the modify/response mechanism

    As you can see, only ‘Manage Frequency Usage’ (part) and ‘Manage Technical State’ provide an interface that allow the subsystems to report their state unsolicited by the CMS. ‘Manage Operational Mode’ provides a definition of where it can provide state information unsolicited, but the standard only states that it will be used when the subsystem needs to change its own state; it does not say that it will also be used when it receives a request to change state from the CMS.

    For the other use-cases, there are the following options:

    • For the use-cases where the state is atomic, assume that the last value on the topic is the current value, not matter what request caused it to be populated. This can only be used for ‘Control Battle Override’ , ‘Control Emissions’, ‘Manage Frequency Usage’ (other part), ‘Manage Operational Mode’ – the others can allow only part of the state to be reported back, depending on what request initiated the published value. This still relies on the subsystem publishing its initial value on start-up.
    • We can assume that all the interfaces use the approach specified in the ‘Manage Operational Mode’ use-case where the full state is reported on a request_id of 0. But then why not just define the interface without the request_id, always reporting all values?
    • Where a request/response interface is specified, the CMS can poll periodically for the state. This only helps us with ‘Manage Subsystem Parameters’ out of those not covered in the options so far.

    That leaves ‘Manage tracking Zones’ and ‘Manage Transmission Sectors’ where none of our options give us a mechanism for discovering the underlying state without changing it.

System Track should have a key

  • Key: OARIS-64
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The system track class is now being used as a topic type and thus requires a key to differentiate individual instances. (See OARIS-3 & OARIS-13).

C++ for general_polar_volume_type does not compile

  • Key: OARIS-41
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The stand alone C++ mapping for general_polar_volume_type does not compile (at least for v6.4 of OpenSplice). This is because the fields within the union have the same name as as their type (also declared in that namespace). Therefore access functions hide the struct declaration below the point at which they are declared.

Name clash between operation and type for transmission_frequency_state

  • Key: OARIS-68
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    There is an operation in the CMS interface for use case Manage Frequency Usage named transmission_frequency_state and a type within the Sensor Control domain model named transmission_frequency_state_type.
    In the DDS PSM, with the generated mappings, this leads to two types named transmission_frequency_state_type. This is at best confusing and can lead to code compilation difficulties (they are generated into different, but related, namespaces).

  • Reported: OARIS 1.0b1 — Wed, 13 May 2015 12:16 GMT

Track Extractors may need to know where Radar is pointing

  • Key: OARIS-63
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    Track Extractor functions may need to know where the (rotating) sensor which is feeding the measurements is pointing at any moment in time. E.g. to know when plots on a particular bearing would be expected to be received. There is not an interface in the OARIS specification to do this, but it is functionally coupled to the provision of plots so the plot_reporting summary use case is a natural home for it.

  • Reported: OARIS 1.0b1 — Tue, 31 Mar 2015 15:13 GMT
  • Disposition: Resolved — OARIS 1.0
  • Disposition Summary:

    Create Provide Sensor Orientation use case

    A new use case within the Plot Reporting summary use case is created (alongside Provide Plots) to provide the sensor orientation to functions such as track extraction. The use case is placed at compliance level 2.
    Following the modeling framework for OARIS, the use case interface (for the CMS) has a single method to provide the orientation of the sensor. The sensor orientation describes its angle (azimuth and optional elevation), the coordinate orientation (using enumerate from Common Types) and its time of validity.
    The coordinate orientation allows for absolute or relative interpretation of angles and defines the zero point for elevation.
    (XMI for the updated model is attached together with a document containing views of updated and new diagrams).

Technical State state transition diagrams omitted from specification

  • Key: OARIS-61
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The UML model for OARIS (from which the specification is generated) contains two state transition diagrams to show the mandatory and superset of transitions between technical states. However, the specification does not include these diagrams (because of the generation template used). The specification consequently lacks some of the intended semantic detail for the class technical_state_type leading to a lack of understanding from users.

  • Reported: OARIS 1.0b1 — Mon, 30 Mar 2015 13:40 GMT
  • Disposition: Resolved — OARIS 1.0
  • Disposition Summary:

    Add state transition diagrams to technical state type

    The document generation should be amended to include state transition diagrams that are members of a class.
    The missing state transition diagram will thus be included in the specification.

Response to a frequency range request to be supported by the PIM

  • Key: OARIS-57
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    In the Manage Frequency Usage use case, if the CMS requests a range of frequencies rather than a discrete set (see class frequency_set_request) then the response from the sensor subsystem does not properly model the subsystem adopting the requested state. Class selected_frequency_list contains a list of discrete frequencies. In particular a list with two frequencies in it is indistiguishable from the expected response to a request to use just those two discrete frequencies - as opposed to the range inbetween them.

  • Reported: OARIS 1.0b1 — Mon, 30 Mar 2015 07:37 GMT
  • Disposition: Resolved — OARIS 1.0
  • Disposition Summary:

    Frequency band to designate a discrete or range of frequencies

    The specification already contains an abstraction of the actual frequencies to use through the frequency band typedef. This class allows a discrete value to be mapped to particular frequencies supported by the sensor. The interface would be simplified without loss of flexibility or rigour by developing the semantics of the frequency_band_type such that it may refer to a discrete frequency or a frequency range.
    The frequency_range_set class is then redundant (as a band may refer to a range) - a range of bands does not in general make sense as it would pre-suppose some logical organisation of the discrete frequency band type that it need not have. Consequently, the frequency_set_request union class is also redundant as there would only be the single way of representing frequency state on the interface as opposed to the current two styles; removing the union is a useful simplification.
    The set_frequencies() method should both take a selected_frequency_list parameter mirroring the transmission_frequency_state() method.
    Metadata pertaining to a frequency band (e.g. whether refers to a discrete frequency or a range) can be communicated using the Manage Subsystem Parameterts use case.

Semantics of sector_added unclear for use case manage_transmission_sectors

  • Key: OARIS-53
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The attribute sector_added :Boolean in class transmission_sector_type has no descriptive text. The semantics of this attribute are not readily deduced, nor can a coherent proposal for what they should be for all instances of the class be formed. For instance, it should be noted that the class is used both for the CMS to request a setting and for the Sensor to report its current state. Equally, there are not attributes to indicate that a sector has been or should be removed.

  • Reported: OARIS 1.0b1 — Thu, 26 Mar 2015 19:06 GMT
  • Disposition: Resolved — OARIS 1.0
  • Disposition Summary:

    Remove attribute sector_added

    Attribute sector_added from class transmission_sector_type should be removed as it is both ill-defined and also unnecessary. Both the CMS and a Sensor are able to deduce which sectors have been added, updated or removed (if necessary for their processing) as each sector has its own unique sector_id. Also, having an attribute sector_added etc. makes it possible for the data to be inconsistent - not a good feature.

  • Summary:

    The description of the Manage Transmission Sectors use case states that sectors with a particular transmission mode can be defined. However, this is not supported in the PIM model - for instance no suitable attribute on transmission_sector_type. Also there is a typo on the bullet heading for Transmission Mode Sectors within the description for this use case.

Request_ack_type/error_reason_type/denial_reason_type needs more identifying information

  • Key: OARIS-45
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    These are generic fields used to describe responses following requests. They are published asynchronously to the original request – the request and response are associated with each other using a common request ID found in each.
    The response information is a free-text String. Though this can represent useful information to convey directly to an operator, it does not allow a specific field to be identified at fault (the original request may be composed of a number of fields). Also, there may be several fields at fault.
    I would suggest the following –
    o Allow multiple denial/error reason fields to be associated with the response rather than just one
    o Add an identifier to the field, which can be a generic string. The identity will be appropriate to the original response e.g. the parameter name at fault with appropriate namespacing, or a null value if the error message refers to the whole request in general (e.g. loss of communication). The format of the error identifier should be defined in the description of the request service/topic.

    Allow multiple error reasons with parameter identifier

    A rejecting request_ack should be able to refer to the particular fields that are at fault and to be able to identify multiple discrete errors (for requests with sets of parameters in particular - e.g. Manage Subsystem Parameters and Manage Transmission Sectors).
    A new struct class denial_type with attributes for the existing reason and zero-to-many parameter reference (new typedef of string) should be added to the model. request_ack_type then composes zero-to-many of these.

    The sensor_track_type class does not allow a track to not have a defined environment value. Whilst the environment may be known or assumed for most cases of a naval radar track, for other types of sensor this is not necessarily the case.

    Environment should be optional in sensor_track_type

    Make attribute environment optional in sensor_track_type - environment_type then continues to enumerate actual environments and so it is possible to use this type in a non-optional (mandatory) context to define an object as being in a definite environment.

  • Disposition Summary:

    Define key fields to define object uniqueness semantics

    Attributes and roles with a <<Key>> stereotype should be defined in the Domain Model so as to define object unqiueness where such concepts exist for the defined classes.
    Classes with such semantics are sensor_track_type and possibly sensor_plot_type. Objects of sensor_plot_type are never updated, therefore all occurrence can be treated as separate instances (objects). Therefore a key is necessary for implementation and is not to be applied to sensor_plot_type (this is convenient as the sensor_plot_id_type is defined as optional).
    For topic types in general the IDL clearly identifies the Topic types and their mapping to PIM operations in the preceding comments. Therefore no further action is required for the identification and definition of OARIS topic types in general.

Sensor Track Set is modelled as a set of ids (int values) in PSM

  • Key: OARIS-21
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    The semantics of Sensor Track Set in the Service Model are that it should contain each Sensor Track by value. However, the DDS / IDL PSM models the class as a sequence of int - i.e. by reference to sensor track instances. Reporting by set is an alternative to reporting individual instances so it is not possible to refer to separately published instances by reference to their id/key value. (Nor does it make any sense to do so).
    This is because the relatiohship in the model is aggregation rather than compoistion and the transformation used maps this to a 'by reference' mechanism rather than a 'by value'.

Class Service Indication Type has unintended id field in DDS/IDL PSM

  • Key: OARIS-23
  • Status: closed  
  • Source: BAE SYSTEMS ( Mr. Simon Mettrick)
  • Summary:

    In package Subsystem Control, the class Service Indication Type has an unintended '_id' attribute generated. This is because the composition on the list type is navigable in the reverse direction - leading to the generation of an unintended reference to the list, when the PIM is transformed. The composition between service list type and service name type has a similar problem in the PIM, but being an enumeration the transformation does not generate an extra attribute.
