Draw More, Work Less Computer Generated DiagramsIQSS Tech talk 2014-01-09 Michael Bar-Sinai

Today:

Why and when computer-generated diagrams make sense?

GraphViz

PlantUML (and, also, UML)

Summary

Why Let a Computer Draw

Work on semantic level

Play with parameters (layouts, skins)

Not that strange (HTML, LaTeX)

Play well with CVSs (git/svn/...)

Easy updates

Inspiration for DSLs/APIs

“drawing graphs since 1988”

Open source, available to most platforms

Mainly Command-line, some GUIs exist

Unified Modeling Language

Developed by OMG, a standard body

A diagram for every aspect of software

Structure, interactions, state, deployment…

Diagrams are also useful outside of the software world

OMG Unified Modeling Language TM (OMG UML)

Version 2.5

OMG Document Number: ptc/2013-09-05

Normative Reference: http://www.omg.org/spec/UML/2.5

Machine Consumable Files:

http://www.omg.org/spec/UML/20131001/PrimitiveTypes.xmi

http://www.omg.org/spec/UML/20131001/UMLDI.xmi

Version 2.5 is formally a minor revision to the UML 2.4.1 specification, having been substantially re-written as solicited by the UML Specification Simplification RFP ad/09-12-10. It supersedes formal/2011-08-05 (Infrastructure) and formal/2011-08-06 (Superstructure).

PlantUML

Creates some UML diagrams from text files

Java component - embeddable

plugins include Netbeans, MS Word, Redmine, servlet…

Use Case

@startuml actor user actor admin !usecase ingest as "Ingest data into the system --- various formats supported " usecase manage as "Manage system === Also make sure the grants are mentioned properly" usecase analyze as "Analyze Data" (Use Zelig) @enduml

Analyze user types, usages for the system, and how they all relate to each other (useful!)

…Summing Up

Sometimes its better to concentrate on the structure, and let the computer do the layout

There are free, capable tools for diagraming

Both GraphViz and PlantUML have numerous features not covered in this talk

Thanks.
