The latest release of B2MML from MESA International includes
lightweight data-interchange format that is easy for humans to read and write
and is easy for machines to parse and generate.
See www.json.org for information on
JSON. It is an open standard for data
exchange that is made up of attribute value pairs and array data types. JSON is
language independent but uses conventions that are familiar to most programmers
JSON is a lightweight alternative to XML and is often used in mobile
JSON Schema is a grammar language for defining the
structure, content, and (to some extent) semantics of JSON objects. See www.json-schema.org for information on
JSON schemas. Schemas specify metadata
(data about data) about what an object's properties mean and what values are
valid for those properties. B2MML-JSON
is derived from B2MML XSD definitions, using XMLSpy2021 from Altova (www.altova.com). B2MML-JSON is a complement to the B2MML XML
format and will remain in sync with any changes to B2MML and ISA-95. JSON is typically used with REST based
message exchanges, and XML is typically used with web service (SOAP) based
The B2MML-JSON schema definition includes all the
transactions specified in ISA-95 Part 5, providing one of the first standard
syntax for fully qualified JSON message transactions. JSON messages can be
exchanged using the ISA-95 Part 6 Message Service model, and the associated
implementation OpenO&M implementation. The OpenO&M ISBM (Information
Service Bus Model) defines both a web service and a REST interface
specification to message exchange systems, and supports the exchange of XML and
JSON messages. See www.mesa.org/en/ws-ISBM.asp
for more information.
This is the first release of B2MML-JSON and it includes all BatchML and BatchML-GeneralRecipe elements. The current B2MML-JSON has all elements in a single file (rather large), but the MESA B2MML committee is looking for feedback from users on the best way to partition and organize JSON Schema files. B2MML-JSON users are encouraged to pick up B2MML V7 from the MESA web site at http://www.mesa.org/en/B2MML.asp. B2MML V7 is also available on Github at https://github.com/MESAInternational/B2MML-BatchML.
