REST API

The REST API is available at https://saas.deltaxml.com/api/content-compare/v1/NISOSTS

Content Compare NISO-STS is a very simple REST API with two endpoints: /compare and /authorise.

Parameter

Description

inputA

REQUIRED

Input A to the comparison. We only display the changes in content from this version.

See information below on how to send input files.

inputB

REQUIRED

Input B to the comparison. We retain the structure of this input in the result file.

See information below on how to send input files.

outputType

Use oxygen-tc(default) to get output using Oxygen processing instructions, or html to get a HTML output.

Authorisation

To make a comparison you will need to set the Authorization header to use your id as a Bearer token, for example:

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
CODE

How to Send Input Files

Files can be sent in two ways: URLs, or as raw XML.

URL inputs
For secure URLs set the Content-Type of the inputA/inputB to text/plain .
Here is an example:

...
----form-boundary-id
Content-Disposition: form-data; name="inputA"
Content-Type: text/plain

https://www.example.com/NISO-STS/inputA.xml
----form-boundary-id
...
CODE

Raw XML inputs
To send raw XML you can send either a raw XML string, or attach an XML file.

Set the Content-Type of the inputA/inputB part to application/xml or text/xml.
Here is an example:

...
----form-boundary-id
Content-Disposition: form-data; name="inputA"
Content-Type: application/xml

<?xml version="1.0" encoding="UTF-8"?>
<content xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.NISO-STS.org/NISO-STS_5-0/xml_schema_flat/descript.xsd">
   <description>
      <levelledPara>...etc...
----form-boundary-id
...
CODE

Responses

200 Successful comparison returns the comparison result.

            <title>Introduction</title>
            <p>Arbitrarily large sequences of values pose a problem for JavaScript Object Notation (JSON) [RFC7159] that is well explained in the motivation for JSON text sequences [RFC7464]. The GeoJSON format [RFC7946] faces the same kind of problem. Geographic datasets often run to the tens of thousands or millions of features. The problem is often amplified by the presence of large arrays of coordinates for each of the features.</p>

            <p>This document describes a specialization of JSON text sequences. A GeoJSON text sequence is a document of arbitrarily large size containing one or more GeoJSON objects (e.g., multiple GeoJSON texts that can be produced and parsed incrementally) and not just a single GeoJSON FeatureCollection, Feature, or Geometry.</p>

            <title>GeoJSON Text Sequence Format</title>
            <p>Defined in prose similar to the description of the JSON text sequence in [RFC7464], a GeoJSON text sequence is any number of GeoJSON [RFC7946] texts, each encoded in UTF-8 [RFC3629], preceded by one ASCII [RFC20] record separator (RS) character, and followed by a line feed (LF).</p>
            <p>The GeoJSON text sequence format conforms to all the rules of [RFC7464] and adds the following constraint: each JSON text MUST contain a single GeoJSON object as defined in [RFC7946].</p>
            <p>Heterogeneous sequences containing a mix of GeoJSON Geometry, Feature, and FeatureCollection objects are permitted. How producers and parsers of GeoJSON text sequences communicate rules for allowed GeoJSON types in exchanged sequences is not specified in this document.</p>

            <label>3.</label>
            <title>Security Considerations</title>
            <p>GeoJSON text sequences have no security considerations beyond those of JSON text sequences [RFC7464] and the GeoJSON format [RFC7946].</p>

        <sec id="s4">

            <title>Interoperability Considerations</title>
            <p>The advantage of using ASCII character RS "0x1e" to denote a text is that sequence producers and parsers need not enforce a canonical form of GeoJSON. Any valid GeoJSON, pretty-printed or compact, can be used in a GeoJSON text sequence.</p>
            <p>A variety of parsers designed for newline-delimited sequences of compact JSON text are deployed on the internet today. While there is no canonical form for JSON texts, and pretty-printed and compact forms are equally valid, GeoJSON text sequences containing compact GeoJSON texts with no internal newlines are more interoperable with existing non-standardized parsers.</p>
            <p>In a distributed system where order and exactly-once delivery of messages are difficult to achieve, GeoJSON text sequences that do not rely on order of texts for extra semantics are more interoperable than those that do.</p>
