HeKatE Cases HowTo

Having some real-life case, the HeKatE Process description, and the skeleton case, follow the steps defined below to submit the new case description.

Preparation

Tools

  1. choose your case, identify sources, files, etc
  2. download tools: VARDA, HJEd, HQEd, HeaRT
  3. prepare runtime environment: SWI Prolog, GraphViz (VARDA), Java SE JDK (HJEd, HeaRT), optionally, for HeaRT integration: Py thon, PHP
  4. test the tools with provided examples, report problems in HaDEs CVStrac

Wiki Setup

  1. choose your test NAME - this is cruicial, should be a single word, lowercase, mycase, e.g. thermostat, cardio
  2. clone the skeleleton namespace hekate_case_skel to your case hekate_case_mycase by copying the pages

CVS Setup

  • checkout the cases modules:
cvs -d :ext:MYLOGIN@charon.ia.agh.edu.pl/mnt/cvs/cvs-hades co hekatecases
  • add your new case:
cd hekatecases ; mkdir hekate_case_mycase ; cvs add hekate_case_mycase ; cvs ci

CVS vs wiki: The simple idea is, that all the files generated by tools (.pl, .xml, .dot, etc.) as well as other uploded files (PDF descriptions, etc) are to be submitted to the CVS using the hekatecases module and the mycase directory, see examples below.

The hekatecases module is then checked automagically into the wiki's media directory. So all the files from the HaDEs CVS module hekatecases are accessible in the

{{:hekate:cases:}}

media directory.

So if you do

cd cases/mycase ; cp /tmp/myfile.png . ; cvs add myfle.png ; cvs ci

then the file will be accessible from the wiki as

{{:hekate:cases:hekate_case_mycase:myfile.png}}

The wiki-visible version of the repository is updated periodically every 30 mins: 1, 31.

Phases

In all the phases at least one separate wiki page is created. The name of the page matches the phase name, e.g. in the Conceptualization a page called hekate:cases:hekate_case_mycase:Conceptualization is to be created.

Some phase can require extra pages, e.g. in the Conceptualization the page hekate:cases:hekate_case_mycase:rules is created.

In most of the pages some extra files generated with the HaDEs tools are generated. These files are to be submitted to the CVS and simply referenced (liked) form the wiki pages. See the hekate_case_thermostat case.

Description

Description

Simply create a comprehensive description in English. Try to use simple short sentences. Provide sources, references bibliography.

Save the description in the file indicated in Description.

If your case is based on some sources in electronical form (PDF, html, etc), submit the to the CVS, besides providing links.

Conceptualization

Conceptualization

Depending on the source of the case, provide the original rules in a separate wiki page (see the skel).

Try to provide or identify vocabulary, i.e. concepts and relations that seem to be important in the case (such a vocabulary can be present in the original case description, e.g. UServ).

Try to provide some observations, insights, ideas, if possible.

Conceptual Design

Conceptual Design

The main phase where the ARDplus model is built. VARDA is to be used as a generic tool. HJEd is to be used as a additional tool.

Number of files have to be generated with VARDA. If everything goes well just run the scipt:

cd varda; ./varda-case-gen mycase

this should generate all the files.

Also, try to model the case form scratch using HJEd. Compare the resulting HML file. Report observatins and differences.

In general three design approches can be considered:

  • general,
  • directed,
  • refined.

Having some original case description, the directed design has to be provided. It is directed, becasue the designer tries to match the orignal rules.

If possible some other approaches should be tried (general), as well as optimizing the directed (the refined).

Attribute Specification

Attribute Specification

In this phase attribute named types and domains have to be specified. Follow the general description of Attributes.

As of now (09.2009) the tool support is only provided by HQEed. Use the HML file generated with VARDA to specify named types and physical attributes. Commit the new file.

Please put the description of attributes in the wiki page! In the future an XSLT translator from HML might be provided.

Prototyping

Prototyping

Use VARDA to generate the XTT prototype. Save both the visual model, as well as the new hml.

In fact, the script should have done it for you.

Pleas compare the Prototype generated by VARDA, with the prototype generated by HQEd (load the -att.hml) file into HQEd and generate prototype).

Logical Design

Logical Design

Load the prototype to HQEd.

Design XTT by:

  • adding rules/rows
  • specifying links

Define states (around 10) from which the inference can be run! (FIXME check if states get saved from HQEd).

Save the new HML file.

Generate HMR.

Test communication with HeaRT!

Formal Analysis

Formal Analysis

In this phase the formal analysis of the model is performed.

Start with the previously defined XTT model.

Perform analysis with HalVA. Comment on results. Try to modify the model in a way that allows to test verification plugins (e.g. remove rules, change attribute values in conditions).

Additionally, try to modify models in a way that allows to test builtin HQEd quality checks.

Physical Design

Physical Design

Start HeaRT.

Run from different states in different modes.

Repeat with saving the full trajectory, save to files FIXME.

Start server. Repreat simulation from HQEd.

Integration

Integration

The minimum requirement is to implement callbacks allowing for an integration with a Java, Py thon, or PHP application.

Use the HeaRT overview and the HowTo.

Commint callback source files to the CVS.

FIXME more description

UML

FIXME Use the XSLT translators implemented by K. Kluza to build a UML representation.

HaThoR

FIXME Use the XSLT translators implemented by J. Szostek-Janik and W. T. Furmańska to build SemWeb representations.

Serialization

FIXME Use the serializers implemented by Ł. Łysik to build Java serialization and Drools model.
