What data is expected?

This data category requires all national laws and statutes available to be available online, although it is not a requirement that information on legislative behaviour e.g. voting records is available. To satisfy this category, the following minimum criteria must be met:

  • Content of the law / status
  • If applicable, all relevant amendments to the law
  • Date of last amendments
  • Data should be updated at least on quarterly

  •   Available in bulk? Yes
  •   Is the data provided on a timely and up to date basis? Yes
  •   Publicly available? Yes(as LexML: Brazilian Legal and Legislative Information Portal published by Secretaria Especial do Interlegis)

The LexML is a (governmental) "voluntary initiative", not an robot (like google) neither an "obligation", but is complete about Federal law, statutes and judgments.

LexML collection of legal metadata have only links to documents, today is not a full-text repository. This metadata includes official links (in general HTML converted-publication) and link to the Official Gazette (original online PDF).

There are no "oficial license", only "inferred license", based on official position about it (copyright law interpretation).

About "machine readable": the metadata is machine readable in XML via the web service, but the legal content in the links is HTML, with no semantic markup or structural conformity. Machine readability in this context is assumed to be referring to legislation metadata, not the legal content itself.

There are ~260000 documents described in metadata repository of Federal law, it is available in bulk. The URL and documentation is available at LexML's dataset page in the Senate's open data catalog.

About "timely and up to date basis": have all (precise) metadata, but "up to date" is not a precise criteria for enacting authorities – they are the metadata publishers.
