The Google Dart team has announced Dart SDK 1.3 which improves the performance of asynchronous server-side code to the point that Dart VM is on par with Node.js, the later using another Google technology, the V8 engine.
Amazon has released a new API, the AppStream API, which allows you to programmatically manage apps hosted on the Amazon AppStream platform. For this API, they chose to build it with the HAL media type. HAL is a minimalist hypermedia enabled media type for building machine-to-machine APIs. Amazon is one of the largest organizations to choose hypermedia as a technique for a public-facing product.
The W3C RDF Working Group has moved the JSON-LD and JSON-LD 1.0 Processing Algorithms and API standards forward to recommended status. JSON-LD is a standard to add "linked data" semantics to JSON.
The recently released Noda Time 1.2 provides support for XML and JSON serialization, text formatting and also includes an assembly that enables developers to handle JSON serialization.
PostgreSQL 9.4 will be reintroducing Hstore as the column type of choice for document-style data. This supersedes PostgreSQL’s JSON support which was introduced in version 9.0 and early tests show it to be significantly faster than MongoDB for some operations.
Serialization and immutable collections do mix in .NET, but only if you look to third party libraries like JSON.NET and protobuf-net.
Many of the presumptions of how slow and resource-demanding "Fat” XML is compared to JSON’s lightweight payload do not hold up to a test David Lee, lead engineer at Marklogic, states after running a "crowd sourcing" experiment with 33 different documents and almost 1200 tests on a multitude of browsers and operating systems.
Node.js has built a user-base and reputation for fast and scalable back-end systems. In a recent edition of the Nodeup podcast, four engineers share their experiences developing APIs using the platform. The conversation covers a range of key concerns including API design, security, testing, documentation, schemas and streaming. But advertising your API as RESTful may not be a good idea.
The recently released Twitter API V1.1 ships with support for JSON and provides an ability to authenticate apps via OAuth1.0a.
Newtonsoft’s JSON.NET has received a pair of architectural updates to make it easier to use in projects that involve third party libraries. The two features are known as DefaultSettings and Extension Data.
JSR-353, the Java API for JSON Processing (JSON-P), has reached final approval ballot this month. JSON-P (similar to JAXP) consists of a Streaming API (similar to StAX) and an Object Model API (similar to DOM). Please note that this API does not include JSON data binding (similar to JAXB), and is unrelated to the more popular JSONP or "JSON with padding".
Create any “flexible” or “extensible” file format and sooner or later a group of developers will start complaining about validation. For JSON, several options are starting to spring up.
If you are building new web services with .NET then OData should be high on your list of frameworks to investigate, especially if you need to support unknown third parties. The technology inherently supports both SOAP and REST style messages with the latter offering ATOM (XML) and JSON representations. This means consumers can pretty much request whatever format is best for them.
Microsoft has announced the availability of WCF Data Services 5.2.0 with support for UriParser and fixes to several bugs.
As JSR 342, the specification for Java EE 7, makes its way through early draft review the expert group is keen to get community feedback on a number of open issues. These include which of the new APIs should be added to the Java EE Full/Web Profile, as well as how to better align CDI with Java EE.
