ows.js: A JavaScript repository from boeckMt

#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);
});
