Full Title or Meme

A Namespace is simply a list of names and some of their attributes.

Context

  • A namespace ensures that all of a given set of objects have unique names so that they can be easily identified.
  • Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts.
  • An Entity is an Object with a name that is unique in some Namespace.
  • A Taxonomy is the simplest form of a namespace.
  • A typical Namespace can be uniquely discovered with a URL.

I am dealing with a particularly interesting challenge, wherein I don't want params that are transferred into a composed Service URL, I want some that are used in other aspects of a resulting request, like a POST body. The rub is that I have many params I would need, and don't want to start adding their generic names to the public namespace, because they are basically Service-specific white_check_mark eyes


9:00 What are we doing about Service specific params used in something other than transference to a composed URL? 9:01 I have this example right now of one possible way I was going to do this: ?messages=method:'CollectionsQuery',tags:'foo','bar',schema:'http://schema.org/MusicPlaylist' (edited) 9:01 Basically one param with multiple subelements 9:01 no standard exists for complex json value representation in params, that I am aware of 9:02 that is the best representation I could think of with the use of unencoded reserved chars

this might be worth a discussion in the ID meeting later today. It is symptomatic of any attempt to create a universal semantic and why past attempts (X12, XML) have not been successful.

Problems

The author first tried namespaces in the early 1980's on X12.3 data dictionaries. Since then XML has supported namespace since the late 1980's.
