Markus Glaser and Robert Vogel auf der SMWCon Fall 13:
This talk covers the experience of Hallo Welt! developers and decision makers, gathered in a real world project: Creating a Software Feature Matrix for the BlueForge website. We want to explain the idea behind the project, share the evaluation process and report about pitfalls and problems.

Transcript

  • 1. FeatureMatrix Wikidata vs. SMW – An experience report
  • 2. FeatureMatrix Wikidata vs. SMW – An experience report Wikidata – An experience report
  • 3. FeatureMatrix Wikidata vs. SMW – An experience report Wikidata – An experience report Wikidata – An experiment report
  • 4. experience Get to know what we know • • • • • • 1 2 What is BlueForge? What is a Software Feature Matrix? Requirements Proposed data model Showcase Implementation experience Wrap-up 3 4 5 6
  • 5. What is BlueForge? Mapping Software for Professionals • Software directory, focus on business software • Target audience • • • • User/enthusiast Decision makers Vendors Consultants • Basis for making informed decisions 1 2 3 4 5 6
  • 6. What is a Feature Matrix? Comparing Software Products • Tool to compare two or more software products • 2-d matrix of available / documented features • Quick visual overview 1 2 3 4 5 6
  • 7. What tool is best? Requirements Specifics of software features • there are variants and forks (e.g. "free" vs. "professional version") • there are versions with new features or different implementations of the same feature • features are not binary, they differ in quality 1 Feature comparison • There are groups / categories of software (Schema) • Features can be added / evaluated within the wiki / wikidata via UI (API) 2 3 4 State of knowledge 5 Claims (Wikidata) vs. propositions (SMW) The vendor says this feature is well implemented  6
  • 8. Wikidata Decision was made for the Wikimedia tool Arguments for Wikidata: • • • • 1 2 Propositions can be qualified Interaction is API-based There is already a UI for entering data ... 3 4 5 6
  • 9. … and we were curious
  • 10. Proposed data model Unstructured data within Client (BlueForge) Wiki • An article represents a piece of software, all versions, all variants i.e. „Joomla“ • A category represents a group of software. A piece of software can be in multiple categories i.e. „Category: Content Management“ 1 2 3 4 5 6
  • 11. i.e. "Joomla!" i.e. "Category:Content Management" 1 2 3 4 5 6
  • 12. Proposed Data Model Structured data within Repo Wikibase = A piece of software (= article on client) A feature • features have qualifiers (since version, user rating, ...) • features have sources (vendor, user) • features have (custom) data types item = property = = Groups (= category on client) Features of a group item property of property (aka schema) Naming is consistent between client and repo  link is by convention 1 2 3 4 5 6
  • 13. showcase 1 2 3 4 5 6
  • 14. showcase There are two systems stage.blueforge.biz stage-data.blueforge.biz (MediaWiki + BlueSpice, role "client") (MediaWiki + Wikibase, role "repo") http://stage.blueforge.biz/wiki/ Special:Version http://data-stage.blueforge.biz/index.php/ Special:Version "stage-data" is currently used as a backend, user interaction only on "stage" 1 2 3 4 5 6
  • 15. Implementation experience Data model can be implemented in Wikidata. Philosopy seems to overlap Architecture seems to be flexible enough Officially not ready for 3rd party use: we are very early adopters :) Schema via UI / tool support 1 2 3 4 5 6
  • 16. Implementation experience Hard to set up, we tried using vagrant but ended with a custom/hacked setup. PHP dependency: do not use <= 5.3.2:Caution, this one is used on Ubuntu 10.04 LTS Custom value types were hard to implement Value autocomplete seems to be resource intensive without additional data stores 1 2 3 4 5 6
  • 17. Wrap-up • Wikidata has great potential as a foundation for custom developments • Most troubles we had where because of the very early version we used • Some concepts of Wikidata ("snaks") are hard to understand in the first place 1 2 3 4 5 6
  • 18. Wrap-up • Development of FeatureMatrix will continue on base of Wikidata. But we consider developing the frontend first and ... • ... updating the backend when Wikidata and it's API is more stable. • Are there any other 3rd party users of Wikidata? Are Wikidata people interested in exchange of ideas / code? 1 2 3 4 5 6
