Literate programming and the semantic web are both concerned with meaning. The semantic web seeks to make the Internet more intelligent by adding what I call "conceptual metadata" (i.e. topical information) to web pages. Pages so annotated become more than just randomly linked bits of text; they become conceptual frameworks of information (i.e. ...

schema.org is only a collection of vocabularies (primarily, but not exclusively, for use with microdata), so this question should be: microdata vs. microformats. And why not invite RDFa to the party? RDFa and microdata are not the same, but similar. microformats however differs from both strongly. If your only aim would be to enhance the display of search ...

RDF is a data model, in a similar way to how JSON is a data model. Notably RDF has a number of save formats (serialization formats), including RDF/XML, N3, Turtle, and others. RDFS is a vocabulary of widely used terms (URIs) to define classes and relationships, etc. Ontologies are generally written using RDFS terms or perhaps terms from something more ...

It seems to me that you're comparing apples & oranges. A machine needs 1 day to produce x units, so, this implies that two machines like the first would need 1/2 day. No, it implies 2 machines can produce 2x units in 1 day. We don't have enough information to know if x is divisible, if the machines can cooperate, if there are external ...

The different technologies of the Semantic stack/cake are trying to solve different problems: Some of them are more flexible but less structured (for example XML), while some others (RDF, OWL) are more rich regarding the structure and semantics of metadata. I agree with you that the Semantic Web (as such) is mostly used in academia, but individual parts of ...

Most basically, the term "ontology" is roughly equivalent to the "domain model". It is the set of all objects that represent real world objects or concepts, including all defined relationships, rules, attributes and other metadata that is known or must be assumed as true about these objects within the bounds of this domain. In the Semantic Web, the ...

Your question makes little sense as is. RDFS is a very basic schema language to express RDF constraints. OWL is more advanced schema to express a complicated ontology. They have absolutely nothing in common with XML except that they can be expressed in XML.

RDF/OWL vs XML is false alternative. In fact one of popular serialization is using XML. Also RDF/OWL vs microformats is false alternative. In fact there are standards that allow using RDF as an microformat, eRDF and W3C's official RDFa with standardized way of embedding it in HTML5. So truly the question is what the advantage of using standard, W3C ...

Couldn't diagree more with ZJR's answer. It is utterly uninformed. How do you parse Microdata? What does it parse too? RDFa parses to RDF, a common data model that is the thing the Semantic Web has been crying out for. Microdata basically came about because Hickie couldn't be bothered to read the RDF and RDFa specs. It might be easier for a developer, but ...

Dont agree one bit with the answer from faif. Basically state of SemWeb is as follows: The really useful standards have only gone into recommendation quite recently. SPARQL 1.0 wasn't that useful, SPARQL 1.1 is UBER powerful. The RDF working group were also put on hiatus delaying the standardisation of Turtle (which is now imminent) and RDFj (RDF and ...

Both concepts appear to target the point where human reading meets computer execution. In literate programming, human readable part is represented by the idea of writing programs like in an ordinary human language, much like the text of an essay. Respective part in semantic web is that it targets human-readable web pages. Computer execution aspect in ...

It is very simple in order to get the meaning so that you can do what you want in the two cases above. You need to parse the sentences so that you can get the following semantics (together with built-in knowledge) A machine has a production speed A truck has a transportation speed The inferred knowledge about the prime/atomic form of the production speed ...

Google's structured data tester shows how well its parsers recognize both their presence together. Schema.org documentation is biased to microdata- invented within Google by WHATWG HTML5 editor. It prefixes RDFa lite reseved words with "item", eg. property=itemprop and so forth. Also it is unsupported outside HTML5. RDFa initial context ...

There is no consensus on these. Both can be used for Google, though Schema.org is the newer of the two and appears to be more comprehensive in my opinion. It boils down to your needs for markup - use what is easier and more suitable to what you are doing.

I suppose it depends on your background, but in order to forget about the persistence layer I'd concentrate on the Objects I'd nedd and use some Object <--> Relational mapping component (e.g. hibernate) instead of relying on a direct integration with text files. You can also work with text files via hibernate >> JDBC >> ODBC >> Text files as stated here ...
