The CSO Open Data Experience
- 1. The CSO Open Data Experience Databank and Dissemination, Central Statistics Office, Cork, Ireland Eoin MacCuirc eoin.mccuirc@cso.ie (00 353 21) 453 5504
- 2. The Tower of Babel “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. Come, let us go down and confuse their language so they will not understand each other.”
- 3. Ireland — Central Statistics Office “The collection, compilation, extraction and dissemination for statistical purposes of information relating to economic, social and general activities and conditions in the State”
- 4. Dublin – 255,000,000 hits looking for a needle in a haystack
- 6. The Web of Things – The Internet of Thingshttp://semanticweb.com/34702/ The Internet of Things is coming, but it needs a semantic backbone to flourish. With some 25 billion devices expected to be connected to the Internet by 2015 and 50 billion by 2020, providing interoperability among the things on the IoT “is one of the most fundamental requirements to support object addressing, tracking, and discovery as well as information representation, storage, and exchange.” So write the authors of Semantics for the Internet of Things: Early Progress and Back to the Future, Payam Barnaghi and Wei Wang, Centre for Communication Systems Research, University of Surrey, Guildford, UK and Cory Henson, Kno.e.sis – Ohio Center of Excellence in Knowledge-enabled Computing. “The suite of technologies developed in the Semantic Web … such as ontologies, semantic annotation, Linked Data and semantic Web services … can be used as principal solutions for the purpose of realizing the IoT,” they state. “Defining an ontology and using semantic descriptions for data will make it interoperable for users and stakeholders that share and use the same ontology.”
- 7. Tim Berners Lee – Founder of the Web “In an extreme view, the world can be seen as only connections, nothing else. We think of a dictionary as the repository of meaning, but it defines words only in terms of other words. I liked the idea that a piece of information is really defined only by what it's related to, and how it's related. There really is little else to meaning. The structure is everything. There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.”

- 9. How open is the data? - Linked Open Data star scheme Tim Berners-Lee suggested a 5-star deployment scheme for Linked Open Data and Ed Summers provided a nice rendering of it. In the following, examples are given for each level. The example data used throughout is 'the temperature forecast for Galway, Ireland for the next 3 days': ★ make your stuff available on the Web (whatever format) under an open license 1 example ... ★★ make it available as structured data (e.g., Excel instead of image scan of a table) 2 example ... ★★★ use non-proprietary formats (e.g., CSV instead of Excel) 3 example ... ★★★★ use URIs to identify things, so that people can point at your stuff4 example ... ★★★★★ link your data to other data to provide context 5 example http://lab.linkeddata.deri.ie/2010/star-scheme-by-example/
- 10. URI – Uniform Resource Identifier give the thing a name and an address The following picture shows the desired relationships between a resource and its representing documents:
- 11. Tim’s cool URIs Cool URIs don't change What makes a cool URI? A cool URI is one which does not change. What sorts of URI change? URIs don't change: people change them. It is the the duty of a Webmaster to allocate URIs which you will be able to stand by in 2 years, in 20 years, in 200 years. This needs thought, and organization, and commitment.
- 12. Where is the CSO with all this? • Publishes data on www.cso.ie • Maintains a statistics portal www.statcentral.ie • Publishes data in JSON-Stat API (Beta) format http://www.cso.ie/webserviceclient/ • One of the first NSIs in the world to upload census data as linked open data – data.cso.ie – Census 2011 http://data.cso.ie/ • Involved in the EU Open Cube project http://opencube-project.eu/ • Hosts data for other government departments http://www.cso.ie/en/databases/ • Actively engaged with the Irish Open Government Partnership http://www.ogpireland.ie/ • Organises the apps4gaps competition www.apps4gaps.ie
- 13. www.cso.ie
- 17. Census – Linked Open Data • 12 million RDF triples from Census • Geographical entities (counties, cities, etc.) • Codelists
- 18. To be delivered December 2015 Open Cube Project Pilots
- 19. • Own the data.cso.ie process and technology – Enable in-house maintenance, changes, etc. • Publish StatBank* data as Linked Open Data – Ongoing publication process – Adhering to release schedule is critical – Publish data that are regularly updated (monthly, quarterly, annual) as linked open data ( Census 2011 static data) *StatBank is the CSO published time series database (PC Axis) • Deploy tools that enable analytics and exploitation of linked data – Both internally and externally CSO goals (independent from OpenCube)
- 20. Public Sector Statistics Network
- 21. www.apps4gaps.ie
- 22. Building capacity – Using the data • Liaison Groups • Seminar Series (Administrative Data and Business Statistics) • Oireachtas Briefings • Social Media (Twitter, YouTube, FaceBook) • Education Outreach (CensusAtSchool, John Hooper Medal for Statistics, IPA Diploma in Official Statistics) • Visualisations and Engagement (Key Economic Indicators, Infographics, Exploristica)
- 23. The Tower of Babel “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. Come, let us go down and confuse their language so they will not understand each other.”

- The data deluge The data deluge refers to the situation where the sheer volume of new data being generated is overwhelming the capacity of institutions to manage it and researchers to make use of it. The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries."[2] The term was coined by Tim Berners-Lee for a web of data that can be processed by machines.[3]

- In computing, a uniform resource identifier (URI) is a string of characters used to identify a name of a web resource. Such identification enables interaction with representations of the web resource over a network (typically the World Wide Web) using specific protocols. Schemes specifying a concrete syntax and associated protocols define each URI. Not to be confused with its two subclasses, uniform resource locator (URL) and uniform resource name (URN). URIs can be classified as locators (URLs), as names (URNs), or as both. A uniform resource name (URN) functions like a person's name, while a uniform resource locator (URL) resembles that person's street address. In other words: the URN defines an item's identity, while the URL provides a method for finding it. A URL is a URI that, in addition to identifying a web resource, specifies the means of acting upon or obtaining the representation: providing both the primary access mechanism, and the network "location". A URN is a URI that identifies a resource by name, in a particular namespace. One can use a URN to talk about a resource without implying its location or how to access it. http://www.w3.org/TR/cooluris/
