ArcGIS Knowledge Web Developer Sample Code

[AdamMartin]

Four new publicly available code samples are available for key ArcGIS Knowledge classes and methods within the Maps SDK for JavaScript in the ArcGIS Developer site. These samples also provide the live knowledge graph services you can hit with the login credentials provided. So no need to spin up your own servers before seeing it in action.

Check them out and let us know what you think! Better yet, share your own samples! 🙂

These samples cover:  

• Knowledge Graph Layer: loading a Knowledge Graph service into a map as a Knowledge Graph layer via REST service url and using inclusion lists. https://developers.arcgis.com/javascript/latest/sample-code/knowledgegraph-knowledgegraphlayer/
• Query: sending an openCypher query to the graph and returning results in JSON and via streaming response. https://developers.arcgis.com/javascript/latest/sample-code/knowledgegraph-query/
• Search: execute a search or streaming search of the Knowledge graph from a simple web form and get JSON response. https://developers.arcgis.com/javascript/latest/sample-code/knowledgegraph-search/ 
• Apply Edits: Sending edits from a web form to add, edit, or delete instances of existing entity or relationships types in your Knowledge Graph. https://developers.arcgis.com/javascript/latest/sample-code/knowledgegraph-applyedits/

I'll note that the 'streaming' query and search methods are key to performance when working with large knowledge graphs and provide optimal user experiences. These samples add depth to the existing Knowledge documentation for the Maps SDK for JavaScript. Be sure to start here: Introduction to Knowledge Graph for the core concepts. 

More samples for Knowledge Graphs in the ArcGIS API for Python are also coming soon...
