Characteristics

Characteristics

  • Free

    • Community ownership, free distribution

  • Source code distribution

    • Users can change the product

  • Peer Review

    • Users can influence the product

  • Distribution

    • No restriction in parties - secondary software

  • Review Board / Committee

    • Decides on core product


Open source basic idea

Open Source Basic idea

The basic idea behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.


Remia xml case

Remia XML Case

  • XML Pattern developed in 2000

    • Data presentation - Data Transfer - Extract Model Info

  • Edge Presentations London - Barcelona - Vegas

    • pattern exchange - forum messages - more exchange

  • Exchanged with 7 parties

    • swap patterns

    • pattern Enhancements, Java Variant by BFM

    • comments, discussions and suggestions

    • large time savings reported

Open source pattern factory

Open source & Pattern Factory

  • Joint development

    • Contents

    • Quality

    • Broad applicability

    • Multi-variant development

    • Programmers participation

  • Distribution

    • Free, no model licencing

    • 17 Participants

    • Mostly positive: “count me in”

    • Combine Pattern Factory and OS

    • CA should support the initiative

    • Best without CA, user community to make it work

    • Open source initiative can make a difference

    • Funny you should mention that

    • Rules and commitments for all participants

    • Just about the only thing that will get the Plex community any improvements to the tool.

    • Developers are not ready to share such resources
