18. EDGE CASES Office of Publications ELI patterns

19. International agreements have no year / natural_number Problem International treaties cannot be uniquely identified using typedoc/year/natural_number Solution For international agreements, use the {year} and {natural_number} of the decision to which the agreement is associated. ELI/eli/{typedoc}/{year}/{natural_number} Exempleseli/agree_internation/1974/654/oj ReturnsSame behavior as with other ELIs

20. Natural number is unique… 99.5 % of the case Problem 2 or more legislation of the same type are published the same year… with the same number. This cannot happen since 01/01/2015 Solution Natural_number will include a sequence number in that case ELI/eli/{typedoc}/{year}/{natural_number}({seqnumber}) Exemples eli/dec/2014/445/oj eli/dec/2014/445(1)/oj Returns If seqnumber is not given in ELI, then return the list of the possible corresponding documents

21. Only one corrigenda corrects a given text in an OJ issue… 99% of the case Problem Some OJ issues are publishing on the same day two or more corrigenda correcting the same base text. So the date of publication is not sufficient to identify them. SolutionIf this is the case, redirect to the Legal Expression level ELI /eli/{typedoc}/{year}/{natural_number}/corrigendum/{p ub_date}/{seqnumber}/oj Exemples Returns If seqnumber was not given by the user (while there was an ambiguity), then the list of all corrigenda correcting the same text and published on the same day must be returned.

22. A text has only one document in each format… most of the time Problem Some texts have 2 files for a given format : one containing the act itself, the other containing the annexes Solution When this is the case, return a list of the possible documents in an HTML page ELIFormat ELI : …/{format} Exempleseli/dec/2011/318(2)/fra/xhtml ReturnsA list of the possible documents in an HTML page

23. Point-in-time access can return a list of document Problem When specifying a point-in-time, or when accessing the abstract legal resource there is 2 behaviors : 1.If there are no pending corrigenda/modifiers, user is redirected to the latest consolidated version or base act; 2.If there are pending corrigenda/modifiers, they should be listed along with latest consolidated version or base act. SolutionReturn a list ELI /eli/{typedoc}/{year}/{natural_number}/{lang} /eli/{typedoc}/{year}/{natural_number}/{lang}/{format} Exemples ReturnsEither a list or redirect to the page
