1 18/April/2017 European Legislation Identifier (ELI) Uniform Resource Identifier (URI) Standard for the electronic Irish Statute Book (eisb). What is it? The European Legislation Identifier (ELI) is a semantic web solution 1 that enables direct access to specific national legislation through a structured, flexible identifier. It creates a common system to identify legislation and its metadata. ELI sets out unique identifiers, metadata and a recommended ontology that, when applied to online legislation, produces a structured reference to legislation that is recognisable, readable and understandable by humans and computers, allowing greater and faster exchanges of data and information. This document sets out the implementation of the three phases (pillars) of the ELI standard on the eisb. For more detailed information on the ELI standard please see the ELI register page on the EUR-Lex web site Link to the ELI register page here. How will it affect the access to the electronic Irish Statute Book? Access to the electronic Irish Statute Book (eisb) will not change. Where information is linked to the eisb using the old addressing system a redirection process will automatically provide access to the legislation at the new address. Following the implementation of the ELI URI standard, all new linked references to legislation on the eisb will use the new standard. The three pillars of the European Legislation Identifier The specifications of ELI have three components, referred to as the three pillars: Pillar I: identification of legislation: HTTP URI templates at the European, national and regional levels based on a defined set of components. Pillar II: metadata properties describing legal resources: Definition of a set of metadata and its expression in a formal ontology. 1 The Semantic Web (also named Web 3.0) is a network of data that enables machines to understand the semantics (i.e. meaning) of information published on the Web. It extends the network of human-readable Web pages (e.g. published in HTML) by inserting machine-readable metadata about that published information and how it relates to the content in other pages, thereby enabling automated agents to access the Web more intelligently and perform tasks on behalf of users.

2 Pillar III: rendering the ELI metadata machine-reusable: Integration of metadata into the legislative websites. When will the first phase of the ELI go live on the eisb? The first phase of the ELI implementation i.e. the standard for the Uniform Resource Identifiers (URI) went live in September What about the second and third pillars? The second pillar has been completed by identifying the relevant ELI metadata properties that apply for the eisb and these values are now documented in the eisb metadata ontology on pages 11 and 12. The third pillar consisting of the serialisation of metadata (i.e. marked up appropriately in RDFa and embedded in the HTML pages) has been completed for 2016 and will be updated for new legislation going forward. An example of this mark-up is available on page 13. The RDFa metadata can be viewed through a browser extension. One example is The OpenLink Structured Data Sniffer (OSDS) which is a browser extension for Google Chrome, Mozilla Firefox, and Opera (with builds planned for Apple Safari, and Microsoft Edge) that unveils metadata oriented structured data embedded within HTML documents. Reading material for further information on implementing ELI The ELI steering committee, through the EU Office of Publications, has published two manuals that cover implementation of ELI in detail; 1. ELI implementation methodology - Good practices and guidelines 2. ELI - A technical implementation guide ELI Video The ELI steering committee has also produced an informative video that is available in 24 languages at the link below; More Information on the ELI URI schema Information on the structure of the ELI URI schema and how it will be implemented on the eisb is set out below...

3 ELI URI general template components Name Comments eli Jurisdiction Jurisdiction Use of DCTERMS.ISO3166 : 2 alpha country codes, e.g. LU For international organisations, the registered domain name can be used: e.g. EU or WTO Agent Sub-agent Administrative hierarchical structure, e.g. Federal States, constitutional court, parliament, etc. Administrative hierarchical substructure, e.g. the responsible ministry Reference Year YYYY Various interpretations allowed depending on countries requirements, e.g. date of signature or date of publication, etc. Month Day Type Sub-type Domain Natural identifier MM DD Nature of the act (law, decree, draft bill, etc.) Various interpretations depending on countries requirements Sub-category of an act depending on countries requirements (e.g. corrigendum) Can be used if acts are classified by themes, e.g. codes Reference or number to distinguish an act of same nature signed or published on the same day Subdivision Level 1 Reference to a subdivision of an act, e.g. Article 15 Level 2 Reference to a smaller subdivision than level 1, e.g. Article 15.2 Level 3 Reference to a smaller subdivision than level 2 Level n Reference to a smaller subdivision Point in time Point in time YYYYMMDD Version of the act as valid at a given date Version Version To distinguish between original act or consolidated version Language Language To differ different official expressions of the same act Use of DCTERMS.ISO3166 : 3 alpha

4 The exact syntax of the URI standard is as follows; /eli/ {jurisdiction}/{agent}/{sub-agent}/{year}/{month}/{day}/{type}/{natural / /{Point in Time}// Using the above as a template the following edited syntax is required for the eisb; /eli/ {year}/ {type} / {Natural / / / {Point in Time} / These elements would contain the following values; name format value comments Year yyyy 2014 Type act prv ca Public Act Private Act Constitutional Amendment si sro cons Statutory Instrument Statutory Rules, Orders and Regulations Constitution (1948 date) ( ) Natural ID nnnn 9, 23, 850 Number of Act or SI or Cons. amendment Level 1 contents section/nnnn schedule schedule/nnnn article/nnnn contents section/1 schedule schedule/2 article/16 Contents (TOC to Long Title) - Section number and Schedule for Acts only. - Article number for Constitution only Version enacted Enacted made Made revised Revised Point in Time yyyy-mm-dd For Revised Acts & Constitution Language en ga English Irish
