Trends from MoDELs 2005

Numbers: 40+6 / 166 papers, 175 participantsDomain Specific Languages– two key note speeches on DSL (and sponsorship from MicroSoft)

Douglas C. Schmidt, Vanderbilt + Juha-Pekka Tolvanen, MetaCase

Aspects / Crosscutting concerns– Domain Models are Aspect Free (F. Steimann) Best paper– Modeling Crosscutting Services with UML Sequence Diagrams

Ingolf Krueger

Educators’ Symposium– Teaching UML 2 is still not very common

Workshops– In MoDELs the workshops are almost small conferences– 2 best of each in an LNCS volume

SPLC 2005 - Software Product Line Conference

Change is Good – you go first– det var kanskje en litt oppgitt erfaring at på tross av mange gode

case studies etc., så er bedrifter tilbakeholdende med å satse på product line teknologi

– Likner litt på SISU / SDL arbeidet vårt, og på UML arbeidet vårt, og på Simula i sin tid

DSL (Domain Specific Languages) her også– Nokia – hva gjør egentlig de?– har skaffa seg Jan Bosch– satser på open source – men er skeptisk til standardisering

Mye prosess, noe modell, noe armveivingGod respons på Birgers foredrag!

SPLC - 2005

A reference model for comparing approaches to the modeling of system families/product lines

What should such a reference model do?– Obviously tell how an approach handles variations,– but, equally important, how an approach covers commonalities – and requirements to systems development in general, e.g.

Analyzability (can system family models be analyzed?)Support for iterative development (partial family models)?Maintenance, evolution (what about not-foreseen features?)

SPLC - 2005

Approaches – Framework/Configuration

”dette er bare implementasjon/design, og hører ikke hjemme i en modell av en klokke!”

– Family-as-the-union-of-all-systems– Domain Specific Languages

Det ble ikke vel mottatt av DSL-fortalere at det ikke var noen systemfamiliemodell der.

Can the system family model be analyzed?

Framework/ Configuration

Family-as-the-union-of-all-systems

Domain Specific Languages

Yes

as the family model is also a valid system model with default structure and behavior

No

as the family model with all variations and all annotations is not necessarily a valid system model

No

as there is no system family model,however, the language may be analyzed

OOPSLA 2005

Det er fremdeles ugjorte ting innen programmeringsspråk (generics, traits, aspects, etc)– kanskje derfor ikke så mye modellering på OOPSLAPanel om aspekter: Passing Fad or New Foundation?– Bekreftet problemstillingen i SWAT– Husk å lese hva du selv skriver!

Panel (Booch, Constantine, Beck, Wirfs-Brock, Yourdon)– Grady Booch kom til å si at han kastet sine UML modeller!

David Reed: Designing Croquet’s TeaTime - A Real-time, Temporal Environment for Active Object Cooperation– ”objects, behave” – non-synchronized communication

Grady Booch: On Creating a Handbook of Software Architecture– Samler sammen erfaringer omkring arkitektur fra en rekke vellykte

prosjekter (ikke mislykte)

Workshops jeg var innom

• Early Aspects: Elisa Baniassad, Joao Araujo, Paul Clements, Paulo Merson– Early Aspects er altså å arbeide med ”crosscutting concerns” i de tidlige fasene av software produksjon,

også når man innhenter krav og ønsker.– Før man har noen struktur er på en måte alt ”crosscutting” til alt annet.– Det hele virket lite fast i fisken, men …– Ivar Jacobson har skrevet en bok om dette: ”Early Aspects = Use Cases” e.l. Bra??

• The 5th OOPSLA Workshop on Domain-Specific Modeling: Juha-Pekka Tolvanen, Jonathan Sprinkle, Matti Rossi, Birger Møller Pedersen

– Det dreier seg om modellering sent i prosessen, slik at de ønsker å kunne generere kode ut fra modellen– Det dreier seg altså om grafiske programmeringsspråk– Jeg foreslo at en blanding av tekst og grafikk måtte være en fornuftig ting, men det slo ikke an. De ville

rendyrke sin grafikk for formålet.– De var lite interessert i UML-aktige notasjoner

Inviterte foredrag• Creativity

Robert Hass– Er poet (!), og snakket om kreativitet ut fra det. Om å observere når man selv er kreativ, og forsøke å

sette seg i slike situasjoner og legge forholdene til rette. Gå en tur?• Why Programming is a Good Medium for Expressing Poorly Understood and Sloppily

Formulated IdeasGerald Jay Sussman

– Skulle jeg gjerne vært på …• Designing Croquet's TeaTime - A Real-time, Temporal Environment for Active Object

CooperationDavid P. Reed

• Finding God DesignMartin Fowler

– Litt forunderlig stil. Snakket mest om ”separation of concerns”. Ikke revolusjonerende• On Creating a Handbook of Software Architecture

Grady Booch– Var dessverre etter at jeg måtte dra, men det skal ha vært interessant …
