Data 3.0 (a Manifesto for Platform Agnostic Structured Data) Update 5

After a long period of trying to demystify and unravel the wonders of standards compliant structured data access, combined with protocols (e.g., HTTP) that separate:

1. Identity,
2. Access,
3. Storage,
4. Representation, and
5. Presentation.

I ended up with what I can best describe as the Data 3.0 Manifesto. A manifesto for standards complaint access to structured data object (or entity) descriptors.

Alex James (Program Manager Entity Frameworks at Microsoft), put together something quite similar to this via his Base4 blog (around the Web 2.0 bootstrap time), sadly -- quoting Alex -- that post has gone where discontinued blogs and their host platforms go (deep deep irony here).

It's also important to note that this manifesto is also a variant of the TimBL's Linked Data Design Issues meme re. Linked Data, but totally decoupled from RDF (data representation formats aspect) and SPARQL which -- in my world view -- remain implementation details.

Data 3.0 manifesto

• An "Entity" is the "Referent" of an "Identifier."
• An "Identifier" SHOULD provide a global, unambiguous, and unchanging (though it MAY be opaque!) "Name" for its "Referent".
• A "Referent" MAY have many "Identifiers" (Names), but each "Identifier" MUST have only one "Referent".
• Structured Entity Descriptions SHOULD be based on the Entity-Attribute-Value (EAV) Data Model, and SHOULD therefore take the form of one or more 3-tuples (triples), each comprised of:

  • an "Identifier" that names an "Entity" (i.e., Entity Name),
  • an "Identifier" that names an "Attribute" (i.e., Attribute Name), and
  • an "Attribute Value", which may be an "Identifier" or a "Literal".

• Structured Descriptions SHOULD be CARRIED by "Descriptor Documents" (i.e., purpose specific documents where Entity Identifiers, Attribute Identifiers, and Attribute Values are clearly discernible by the document's intended consumers, e.g., humans or machines).
• Structured Descriptor Documents can contain (carry) several Structured Entity Descriptions
• Stuctured Descriptor Documents SHOULD be network accessible via network addresses (e.g., HTTP URLs when dealing with HTTP-based Networks).
• An Identifier SHOULD resolve (de-reference) to a Structured Representation of the Referent's Structured Description.

Experience is not interesting till it begins to repeat itself, in fact, till it does that , it hardly is experience.

Mostly I don’t come up with upon blogging sites, but I want to say that this document extremely asked others to do this! Who would have thought, fairly wonderful provide.

je comprend « je ne suis pas fière… »mettre en évidence une situation personnelle vis à vis de chaque regard est un peu flippante au début. Ceci n’ a rien à voir avec le désir d’enfant ou même de la beauté de son corps. il est naturel de vouloir se préserver, ne pas offrir au premier venu la possibilité de franchir la line de l’intime.

ayant eu une grossesse de jumeaux , les premiers mois je semblait « très grosse » d’où les regards chargés de morale…, bien sûr j’avais pas affiché :
1) qu il y avait 2 bébés,
2) que j’avais manger des hormones pour 10 puisque grossesse par FIV…à la fin de ma grossesse,

safety, and comfort of others are not disturbed. Behavior inconsistent with these values could lead to administrative action and/or a hearing by the Committee on Student Conduct. Such cases may also result in civil action and/or action by the Dean of the College or designee.

The statement is subjective. Better to get straight to the point.

Carefully navigate finished your article , which you put forward those views I agree . These views contain a lot of philosophical knowledge , as well as the lives of some very helpful knowledge . A lot of people believe that knowledge and common sense will bring benefits .
