DCR XML Log – the foundation for Declarative Process Mining

A DCR XML Log format is defined in an XSD Schema which can be accessed here. The DCR XML format and DCR XML Log format is the intellectual property of DCR Solutions and any use of this format requires a commercial license.

Classic process mining use the XES format for mining.

This document proposes an XML format for serializing DCR runs. Recording traces comes up in several contexts:

  • Input for the “Simulation Log” in the simulator in the portal
  • Input for the flow visualiser
  • Output of the path analyser
  • Data structure for saved simulations
  • (Potential) data structure for DCR logs in a process mining context

The format below attempts to cater to all of these.

One could imagine a log format that is relative to a DCR model. Such a format would not need to represent explicitly roles or labels, as these would be reconstructible from the DCR process model. The present format does not attempt such minimality, opting rather to be complete enough for all of the above purposes.

2, 4, and 5 does not have such a context DCR model.

NB! A log processor must preserve labels and nodes not mentioned in this document.

Log format

A log is a collection of traces:

<log>

<trace>

[ entries ]

</trace>

<trace>

…

</trace>

</log>

Each log has an optional attribute called “logtype” which can be either “log” or “scenario”. A “log” comes from an IT system like DCR Open Case Manager, SBSYS or KMD WorkZone. A “scenario” comes from the DCR portal. A scenario never includes timestamp attribute on events.

Trace format

A trace is a sequence of entries, where an entry is either an <event> element, an <advance> element, the former indicating the execution of an event, the latter that time advanced, a <note> element, a trancation element or a <subprocess> element.

The <trace> element has the following attributes:

  • Mandatory attributes
    • init – initialization time of trace
    • id=”19-1234″
    • created – created date of the trace
  • Optional attributes
    • title=”my very first trace”
    • description=…
    • content=… – the context in which the trace is executed
  • For scenarios – the following attributes are mandatory
    • isAccepting – true/false
    • percentage=”7″ – how often does this trace occur in the overall list of traces (scenario log)
    • type – required, neutral, forbidden (scenario log)
    • businesstype – asis, tobe, none
    • isScenario – true/false (scenario log)

The <event> element has the following attributes. Attributes not explicitly
marked as “mandatory” are optional.

  • id=”A”. The id of the event to execute. Mandatory.
  • timestamp=”2017-04-27T09:55:45.4412580+02:00″. The physical time in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) of the execution of the event.
  • user=”Thomas”. A string identifying the user requesting the execution of the event. The interpretation of the string is implementation specific.
  • userid=”1234″. A string identifying the user uniquely. If prefixed with “portal:” it is a userid from the DCR portal.
  • role=”doctor”. The role under which the user executed the event. Multiple roles are permitted and must be separated by commas. Each role must be a “role” of the (an) underlying DCR process.
  • label=”Administer medicine”. The DCR label of the event.
  • missedDeadline=”2017-04-27T09:55:45.4412580+02:00″. This attribute indicate that the event was executed after a deadline which is provided.
  • data=”9″. The data-value supplied as input.
  • ‘type’=”int”. If data is provided the internal C# data type must be present so log verification knows the type of data

The <advance> element has the following attributes.

  • delta=”7″. The duration to advance time in ISO 8601 duration format (https://en.wikipedia.org/wiki/ISO_8601#Durations). Mandatory.
  • durationFrom=”<duration>”. Optional.
  • duratinTo=”<duration>”. Optional.
  • description=”<description of duration>”. Optional

The <note> element has the following attributes.

  • id=”A”. The id of the event to execute. Optional.
  • comment=”this is a comment”. A comment entered by the end user. Optional.
  • timestamp=”2017-04-27T09:55:45.4412580+02:00″. The physical time in [ISO 8601]. Not relevant for scenarios.

The <transaction> element has the following attributes.

  • id=”A”. The id of the event to execute
  • timestamp=”2017-04-27T09:55:45.4412580+02:00″. The physical time in [ISO 8601

Inside the transaction element any other element, i.e. <event> can occur. This is used for DCR Forms.

The <subprocess> element has the following attributes

  • id=”A”. The id of the subprocess to execute
  • timestamp=”2017-04-27T09:55:45.4412580+02:00″. The physical time in [ISO 8601]. Not relevant for scenarios.

Moreover, the <advance> element admits “user” attributes, with syntax, requiredness and semantics as for the `event` element.

Example

<log>
<trace id=”19-1234″ title=”My very first trace” percentage=”90,00″  init=”2020-01-02T15:39:25.4577929Z” context=”…”>

<event id=”A” label=”Administer medicine” data=”‘8cc’” type=”string”/>

<event id=”T” label=”Receive permission” timestamp=”2017-04-27T09:55:45.4412580+02:00″ />

<note id=”A” comment=”I do not understand why this event is still in the task list” />

<event id=”Process[0].A” label=”Initiate investigation” user=”Morten Marquard” role=”Doctor” timestamp=”2017-04-27T09:55:45.4412587+02:00″ />

<advance delta=”P0Y0M7D” />

<transaction id=”Form”>

<event id=”Amount” label=”Please enter amount” user=”Morten Marquard” role=”User” data=”123456″ timestamp=”2017-04-27T09:55:45.4412587+02:00″ />

<event id=”GDPRConsent” label=”Please accept GDPR” user=”Morten Marquard” role=”User” data=”true” timestamp=”2017-04-27T09:55:45.4412587+02:00″ />

</transaction>

<advance delta=”P0Y0M5D” user=”Thomas Hildebrandt (hilde@itu.dk)” timestamp=”2017-04-27T09:55:45.4412580+02:00″ />

</trace>

</log>
