Detail with developer tools open, on inspecting client-side methods operating a SoQL Socrata Query across all eight API endpoints (2009–2016) at NY’s Dept of Health. (A) shows the execution in the MathBiol console; (B) shows the same operator used to generate a list in HTML and the resulting table; (C) shows the code behind the count command, which migrated to the user’s browser from mathbiol.github.io/sparcs/sparcs.js (see Availability in ‘Methods’); Finally, (D) shows the same command being recognized after negotiating variations in the syntax (“TypeError”) used to call it. For clarity, the programmatic count call resulting from “assuming sparcs.count()” is also executed manually at the end of that negotiation. That is, the imprecise syntax of the command in the console (A) was caught (see error message in D) and an alternative syntax was found. This error catching approach allows for looser syntaxes in the user-interface (A), illustrating the opportunity to devise Domain Specific Languages (DSL).
