 Collections of links can be attached to various elements in SDMX-JSON.
 
-Similarily with standards such as HTML5 and Atom, link elements in SDMX-JSON *must* define a *URL* (the `href` attribute) and a *semantic* (the `rel` attribute). This allows clients to follow the links they care about and ignore the ones whose semantic they are not interested in. In addition, links in SDMX-JSON *may* define a `title` (a human-friendly description of the target link) and a `type` (a hint about the type of representation returned by the link). Please refer to the [list of Media Types and Subtypes](http://www.iana.org/assignments/media-types/media-types.xhtml) assigned and listed by the IANA for additional information about expected values for the `type` attribute.

 SDMX-JSON offers a list of predefined semantics, but implementers are free to extend it. The list of predefined semantics comes from the list of SDMX artefacts that can be returned by SDMX RESTful web services, semantics defined in [RFC5988](https://tools.ietf.org/rfc/rfc5988.txt) and additional items deemed to be useful in the context of statistical data dissemination.
