  1. Strategies for web based data disseminationA strategy is a plan of action designed to achieve a vision - from Greek "στρατηγία" (strategia). United Nations Regional Workshop on Data Dissemination and Communication Rio de Janeiro, Brazil, 5 - 7 June 2013 Zoltan Nagy – Statistics Division, Department of Economic and Social affairs, United Nations

  2. Existing Strategies • Fundamental Principles of Official Statistics “statistics that meet the test of practical utility are to be compiled and made available on an impartial basis by official statistical agencies to honor citizens' entitlement to public information” • Handbook of Statistical Organizations • National Strategies for the Development of Statistics (NSDS) • The Generic Statistical Business Process Model (GSBPM)

  3. Data dissemination = communication ECONOMIC AND SOCIAL PROGRESS Policy making Professionals & public Policy validations Knowledge based society Policy accountability Policy decisions Communication Policy options Analysis & research Communication Statistical needs and education Analysis & assessment INDEPENDENT OFFICIAL STATISTICS

  4. The importance of web-based data-dissemination • From 2008 to 2013 the number of Internet users grows by 67% • Everyone who has access to internet is becoming a potential user of statistics. Forget the last war.

  5. Identifying users • User groups • Decision makers (government at central and local level, businesses) • Academia (institution that use, research and analyze data) • Educational (primary, secondary, tertiary) • Public at large • Tourists Harvesters and (data) Miners

  6. Tourists • Novice or infrequent users, and typically make up the majority of individual users. • Looking for basic data either out of curiosity, or to inform personal decisions. • Want to be able to find and view data quickly and easily, they prefer low levels of complexity and need only limited functionality.

  7. Harvesters • Intermediate and fairly frequent users, who are looking for data to inform basic research or economic decisions. • They will accept increased complexity if it results in addition functionality and flexibility in the way they can view and download data.

  8. (Data) Miners • Expert users, typically small in number, but using large volumes of data on a regular basis, often for detailed research or analysis. • They want simplicity, easy downloads functionality and flexibility, take data offline

  9. A new type - Builders • Experts that want to reuse statistical data without copying or downloading it. • Requesting ability to access data servers at 24/7 and feed data to maps, visualizations and other applications. • Web services - interoperable machine-to-machine interaction over a network". • Mashups – hybrid web applications • Visualizations • Mappings • Data aggregators

  10. Defining the content • Data • Topic – domain specific or across-domain • Coverage – geographical and time • Aggregation level - micro and macro data • Nature of the data – tables, tabulations, time-series, datapoints • Documentation • Metadata (descriptive and structural) • Methodologies and standards • Classifications • Best practices, business processes, etc.

  11. Subscription models • Registration • No registration required • Registration required (provides better tracking, communication etc) • Subscription • Free (preferred by many countries) • For fee (cost recovery, profit, one-time, periodical, service based ) • Multi-tier (free basic and for fee premium services)

  12. User management • User access (registered vs unregistered users) • User support, helpdesk • User surveys (online polling) • User activity tracking • Web server statistics • Analytic services (Google analytics) • Custom built tracking services • Social networking (Facebook, Twitter..)

  13. Site administration • Data Management • Data correction facility • Data upload facility • Data availability • Metadata Management • Structural metadata • Descriptive metadata • Data upload calendar • Management Reporting

  14. Resource allocation • Data dissemination group (Centralized or Decentralized) • Systems/Application development • Hardware and software requirements • Long-term maintenance • Operation • Helpdesk -------------------------------------------------- = TOTAL COST OF OWNERSHIP (TCO)

  15. Content delivery • Bandwidth conservation • Browser considerations

  16. Mobile devices

  17. Software platform and architecture • Off-the-shelf products • Custom development (in-house, outsourcing) • Open source platforms • Proprietary platforms • Self hosting • Outsourced hosting

  18. Design considerations • Simplicity and ease of use • Easy of navigation • Bookmarking • Searchability • Drill down • Dimensional search • Full text search

  19. Conclusions • One size does not fit all • Web-based data dissemination should work as a two way communication • Focus has to be on users who frequently visit our sites • The maintenance of web-based data-dissemination products is a long term commitment • We have to be aware of TCO
