Rethinking public sector data ecosystems - Open Government Data, Semantic MediaWiki and Wikidata - Wikimania 2019

258 Aufrufe

Veröffentlicht am

In the session the question will be discussed how data from the public sector is generated and made publicly available. Very often, cumbersome processes are in place until finally data (e. g. from official statistics) reach Wikipeda. Often this is done through publication in Open Government Data portals and voluntary efforts to add official data as source in Wikidata.

In the talk, a redesign of the ecosystem of how public sector data is generated, distributed and made available will be presented, facilitating Semantic MediaWiki as data tool. The relation to Wikidata/Wikibase, Open Governmen Data portals and official statistics will be discussed.

  2. 2. www.kdz.or.at Introduction  KDZ – Centre for Public Administration Research  Open (Government) Data  Semantic MediaWiki 17. August 2019 · Seite 2
  3. 3. www.kdz.or.at Open Data – a short introduction  Open Government Data means data from the public sector that is published for everybody to use without restrictions  Several Open Government Initiatives exist on municipal, regional and federal level  The European Data portal collects information about metadata published by member states  So you need:  metadata describing the data (type, format, license…) -> data.gv.at  a place where you can actually retrieve the data -> URL  Very often open data is the source for Wikidata/Wikipedia 17. August 2019 · Seite 3
  4. 4. www.kdz.or.at Semantic MediaWiki – a short introduction  „Older sibling“ of Wikidata  Ecosystem of extensions around managing data in your own MediaWiki  Enterprise ready, used in many large wikis (open or closed) outside of WMF  Commercial support available  SMW installations can be datasource for Wikidata 17. August 2019 · Seite 4
  5. 5. www.kdz.or.at The problem: We live in the age of big data… 17. August 2019 · Seite 5 …but still a lot of data is missing, closed or old, especially data from „official“ sources (public sector data)
  6. 6. www.kdz.or.at Examples for data needed to monitor SDGs (on local level)  Children in child care facilities (SDG 4)  Number of male/female officials /public servants (SDG 5)  Expenditure for renewable engergy (SDG 7)  Quality of housing (SDG 10)  Public parks (SDG 11)  Amount of waste managed (SDG 12)  Bike routes (SDG 13)  … 17.

  8. 8. www.kdz.or.at Example: Modal split 17. August 2019 · Seite 8  Wikidata: entity, but no data  Nothing in Wikipedia city articles  Manual list in article „Modal share“ https://en.wikipedia.org/wiki/Modal_share https://de.wikipedia.org/wiki/Modal_Split
  9. 9. www.kdz.or.at Example: Modal split 17. August 2019 · Seite 9  Data from 2006, 2016 and 2006 in  Nothing in Open Data Portals  Nothing at Statistics Austria
  10. 10. www.kdz.or.at Data ecosystems: central register Example: inhabitants 17. August 2019 · Seite 10  Cities register new residents in a central database (ZMR)  ZMR delivers data quarterly to Statistics Austria  Some cities publish their own statistics on open data portals (data.gv.at)  data has to be added to Wikidata manually
  11. 11. www.kdz.or.at Possible solution: API, open data  City delivers data to central register  register offers (part of) data in API  Statistics Austria, open data portal and other users (Wikidata) can access data  Probability: somewhat likely 17. August 2019 · Seite 11
  12. 12. www.kdz.or.at Data ecosystems: finances 17. August 2019 · Seite 12 03/2019 (data from 2018) 10/2019  City agrees on spending report and send spending data to regional government  Regional government sends data to Statistics Austria  KDZ buys data from Statistics Austria and publishes them on www.offenerhaushalt.at  Metadata gets delivered to open data portal (data.gv.at)
  13. 13. www.kdz.or.at Possible solution: publish often  City delivers data several times  Probability:  high for open data (already done)  unlikely for Wikidata: (not going to happen!) 17. August 2019 · Seite 13 mandatory voluntary voluntary (?)
  14. 14. www.kdz.or.at Possible solution: municipal data infrastructure  Cities operate a data infrastructure with data input and API/export possibilities  data can be exported to/consumed by many  probability: likely for some data 17. August 2019 · Seite 14
  15. 15. www.kdz.or.at Example: Publication „Austrian Cities in Figures“ 17. August 2019 · Seite 15 3 data sources  Statistics Austria  regional governments  questionnaire for participating municipalities

  18. 18. www.kdz.or.at Result: „Austrian Cities in Figures“   only PDF publication is planned  ~ 75 cities are included (2098 municipalities)  data from 2018 will be published in the document „Cities in Figures 2019“ that will be available in early 2020  Data will not be available electronically  No open license   SMW has proven to be a reliable infrastructure  Easy form based entering of data  Own publication process „approve data“, without wiki know-how  CSV, RDF, JSON export for reuse oft data  Visualisation options (“result formats”) 17. August 2019 · Seite 18
  19. 19. www.kdz.or.at How to improve the situation: Basic steps 1. Convince public institutions to open up data you need: open license, machine-readable format & infrastructure 2. Publish metadata on open data portals infrastructure is there, DCAT-AP 3. Put (some of) their data into Wikidata – as an additional usecase 17. August 2019 · Seite 19
  20. 20. www.kdz.or.at How to improve the situation: Things to consider If they need to build an open infrastructure, there are 3 options: 1. Open up existing infrastructure (API)  2. Change to different infrastructure  3. Donate to open infrastructure (Wikidata, Commons)  4. Build up open infrastructure  17. August 2019 · Seite 20
  21. 21. www.kdz.or.at Options?  Man use case: runs Wikidata  Complex installation  User interface for entering and querying data too complex  Where provenance metadata is essential  For integration with Wikibase  Main use case: manage data in your own wiki  Simple editing using forms  Editing restricted to specific user groupos  Managing text and data  https://www.semantic- mediawiki.org/wiki/Help:Refere nce_and_provenance_data 17.

  23. 23. www.kdz.or.at Lets work together on bringing the best data out of public institutions so everyone can use them as simple as possible! 17. August 2019 · Seite 23  Current data ecosystems are very complex, cumbersome and old-fashioned and therefore slow  There is not enough open data available Summary
