Support for JSON5 in Altova MissionKit, Server Products, and MobileTogether

Altova products have supported JSON for several years. Now, Version 2017 Release 3 of MissionKit and Server products, and MobileTogether Version 3.2 all include support for JSON5 across the product line.

The JSON data format was originally designed to be machine-written and consumed, promoting efficient communication between servers. Usage has expanded and JSON5 is a proposed extension intended to make JSON code easier for humans to write and read.  JSON5 extends JSON by adding some ECMAScript 5 features and, like JSON, is a strict subset of JavaScript. Specifically, JSON5 permits inline and block comments, allows long strings to be split over several lines, and defines alternate legal syntax options for quotes and commas.  These features are not permitted in standard JSON, so files containing the proposed enhancements are typically identified with the .json5 filename suffix.

This post details specific support for JSON5 in each Altova product.

Expect the Unexpected – Altova MissionKit Solves a Number Format Mystery

Every time you receive data from an outside source, there is a chance it won’t arrive in the form you expect. This can require special accommodations for the rare and unlikely to make a real-world data mapping and transformation solution robust and reliable.

We processed literally dozens of .gpx files, containing hundreds of coordinates each, through the MapForce mapping we wrote about in the blog post Web Service as a Look-Up Table to Refine GPS Data. Then one day we ran a new file and encountered the error below, which caused the mapping to fail:

Reaching into the Altova MissionKit to combine features of MapForce and XMLSpy, we quickly diagnosed the issue and developed a solution we can also reuse in future mapping projects.

The Altova MissionKit 2013 Introduces Seamless Integration of XMLSpy, MapForce, and StyleVision in Java Applications

The Altova MissionKit 2013, empowers developers to integrate XMLSpy, MapForce, or StyleVision functionality seamlessly in custom Java applications for Windows. This frequently-requested capability adds to existing support for integrating these MissionKit tools in Visual Basic or C# applications, giving developers flexibility to add some or all XMLSpy, MapForce, or StyleVision views and functionality to their own custom apps.

Version 2013 of XMLSpy, MapForce, and StyleVision include a new API that allows each to run inside a window within a Java application developed using the Java Abstract Window Toolkit (AWT) or Java Swing. This functionality allows MapForce 2013, for instance, to be embedded in larger applications where data mapping and transformation is only one requirement.

Altova provides sample applications with XMLSpy, MapForce, and StyleVision illustrating use of the Java API. You can access the sample applications from the command line or from within Eclipse.

Web Service as a Look-Up Table to Refine GPS Data

Elevation data recorded by GPS devices is notoriously inaccurate, especially in hilly terrain like the Russian River Valley example from our earlier post.

The final elevation track plotted from the Russian River Valley GPX file is suspicious for several reasons. First, the graph shows we descended almost 50 feet below sea level. That’s hard to believe, since we were travelling along the bank of the river, only about 10 miles from the Pacific Ocean.

We can evaluate the recorded GPS elevation data by comparing it to information available from the United States Geological Survey (USGS). The USGS operates a Web service that accepts latitude and longitude coordinates, and returns elevation data measured by NASA and assessed for accuracy based on over 13,000 control points in the continental United States.

Using the elevation Web service in an Altova MapForce mapping will let us extract each point from the GPX file, send the coordinates to the USGS Web service, and build a new GPX file with corrected elevation data.

Resist Data Integration Redundancy

The Internet makes massive amounts of data available for lots of interesting applications. But whenever you design a unique analysis and presentation of information you don’t privately control, you risk that the owner will offer the same view at some point in the future, instantly making your application redundant.

That’s exactly what happened to the Groupon API data-mining project we originally wrote about in August, 2011. Fortunately, the core of our project is a MapForce graphical data mapping. We can quickly and easily tweak the mapping and repurpose it to present an entirely different data set that provides new value.
