Binary XML is typically used in applications where the performance of standard XML is insufficient, but the ability to convert the document to and from a form (XML) which is easily viewed and edited is valued. Other advantages may include enabling random access and indexing of XML documents. The major challenge for binary XML is to create a ...
^ Omitted XML elements are commonly decoded by XML data binding tools as NULLs. Shown here is another possible encoding; XML schema does not define an encoding for this datatype. ^ The RFC CSV specification only deals with delimiters, newlines, and quote characters; it does not directly deal with serializing programming data structures.
Extensible Markup Language ( XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
Efficient XML Interchange ( EXI) is a binary XML format for exchange of data on a computer network. It was developed by the W3C's Efficient Extensible Interchange Working Group and is one of the most prominent efforts to encode XML documents in a binary data format, rather than plain text. Using EXI format reduces the verbosity of XML documents ...
Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
Using XOP avoids this by extracting the binary data out of the XML Infoset so that the XML Infoset does not contain binary data and the binary data can be serialized differently. Therefore, XOP can reduce the size of the serialization (since base64 encoding has approximately a 33% size overhead) and (depending on how it is implemented) might ...
However, in practice they are quite different: ASN.1 defines a data structure, which can be encoded in various ways (e.g. JSON, XML, binary). ABNF, on the other hand, defines the encoding ("syntax") at the same time it defines the data structure ("semantics").
Fast Infoset (or FI) is an international standard that specifies a binary encoding format for the XML Information Set ( XML Infoset) as an alternative to the XML document format. It aims to provide more efficient serialization than the text-based XML format. FI is effectively a lossless compression, analogous to gzip, for XML, except that while ...
