ows.js

OGC Web Services Library for JavaScript.

This Library is based in the awesome work of Jsonix & ogc-schemas libraries.

Implemented so far

• Basic Ows operations (ex: GetCapabilities)

• CSW

  • GetRecords
  • GetRecordById
  • GetDomain
  • GetCapabilities (Refactored)
  • Transactions:
    • Create
    • Update
    • Delete

• OGC Filters

  • Operators:
    • Logical Operators:
      • AND
      • OR
  • Spatial Operatos:
    • BBOX
  • Comparison
    • isLike
    • isBetween
    • isEqualTo
    • isLessThanOrEqualTo
    • isGreaterThan
    • isLessThan
    • isGreaterThanOrEqualTo
    • isNotEqualTo

Next TODOS

• Clean Ows.js deprecated code.
• Implement NOT operator.
• PropertyIsNull
• Improve Unit-Tests (Help is extremely Welcome here :D)
• DescribeRecord

in the Future

• WPS
• WFS
• SLD
• etc...

Getting started

How to install ows.js in your project.

It is recommended to use bower, because this project depends on Jsonix and Ogc-schemas libraries.

 bower install ows.js --save

Using and configure CSW

The CSW standard strongly depends on catalogues profiles. So first you need to determine what profile you want to use and include its depencies:

Basic CSW

Include in you project:

<script type="text/javascript" src="../bower_components/ogc-schemas/lib/OWS_1_0_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/DC_1_1.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/DCT.js"></script>
<script type="text/javascript" src="../bower_components/w3c-schemas/lib/XLink_1_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/CSW_2_0_2.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/Filter_1_1_0.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/GML_3_1_1.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/SMIL_2_0_Language.js"></script>
<script type="text/javascript" src="../bower_components/ogc-schemas/lib/SMIL_2_0.js"></script>

Configure CSW:

var cswConfig = [
            [
                OWS_1_0_0,
                DC_1_1,
                DCT,
                XLink_1_0,
                SMIL_2_0,
                SMIL_2_0_Language,
                GML_3_1_1,
                Filter_1_1_0,
                CSW_2_0_2,
                GML_3_1_1
            ],
            {
                namespacePrefixes: {
                    'http://www.opengis.net/cat/csw/2.0.2': 'csw',
                    "http://www.opengis.net/ogc": 'ogc',
                    "http://www.opengis.net/gml": "gml",
                    "http://purl.org/dc/elements/1.1/":"dc",
                    "http://purl.org/dc/terms/":"dct"
                },
                mappingStyle : 'simplified'
            }
        ];

Make a request

Simple

var cswConfig = ..... ; //
var csw = new Ows4js.Csw('http://youcatalogueurl/', cswConfig);

csw.GetRecords(1,10).then(function(result){
    console.log(result);
});

With a ogc-filter

var cswConfig = ..... ; //
var csw = new Ows4js.Csw('http://youcatalogueurl/', cswConfig);

var filter = new Ows4js.Filter().PropertyName('dc:title').isLike('%water%');
filter = filter.and(new Ows4js.Filter().PropertyName('dc:subject').isLike('%polution%'));
filter = filter.and(new Ows4js.Filter().BBOX(-80, 150, 80, -150, 'urn:x-ogc:def:crs:EPSG:6.11:4326'));


csw.GetRecords(1,10, filter).then(function(result){
    console.log(result);
});
