The most expansive form using tag pairs results in a much larger (in character count) representation than JSON, but if data is stored in attributes and 'short tag' form where the closing tag is replaced with />, the representation is often about the same size as JSON or just a little larger. However, an XML attribute can only have a single ...
The UTF-8 representation of the BOM is the (hexadecimal) byte sequence EF BB BF. The Unicode Standard permits the BOM in UTF-8 , [ 4 ] but does not require or recommend its use. [ 5 ] UTF-8 always has the same byte order, [ 6 ] so its only use in UTF-8 is to signal at the start that the text stream is encoded in UTF-8, or that it was converted ...
JSON-LD is designed around the concept of a "context" to provide additional mappings from JSON to an RDF model. The context links object properties in a JSON document to concepts in an ontology.
