Media Links Updated 12/4/2024 Miami-Dade County Emergency Management Operations  From User Conference Plenary (7m 32 sec) In the final segment of Miami-Dade County demo, they show how they can leverage ArcGIS Knowledge and Microsoft Teams to staff emergency shelters with the best available people rapidly at a critical time before a storm. Using graph queries accessible directly in a web map, they present an innovative way to rapidly match Employees to Shelters based on unique skills to emergency shelter needs. With knowledge graphs powering advanced pattern-matching, ArcGIS becomes a critical operational and intelligence system. This example link chart above illustrates how an employee (Emp 315712) matches with an open Assistant Shelter Manager role at the Miami Northwestern Senior shelter with the right skills and training - and no pet allergy -  needed for that role. AND this person met the criteria of being previously assigned to a nearby shelter that was not activated for this emergency (Miami Edison Senior in grey) . This image was captured in the ArcGIS Knowledge Studio web application.   This snapshot in ArcGIS Pro desktop application shows how spatial relationships, including the proximity between employees (using fake locations) and Emergency shelters are captured in our graph, as well as the proximity to high concentrations of Creole-speaking populations.  Watch CIO Jose Lopez and Jose R. Rodriquez show this part of the Mayor’s “No Wrong Door” initiative to unite government services for a diverse community and culture.  Arson Investigation  From the Esri Safety and Security Summit (3 min 50 sec) ArcGIS enables analysts to investigate crimes and conduct link analysis and spatial analysis across a variety of intelligence sources within one analytic system. This example by Ollie Brown follows an intelligence analyst’s investigation into potential arson surrounding several large wildfires across Australia where authorities received tips about a person that may have been involved, and collected phone device record data (using fake locations). Using ArcGIS AllSource desktop application with the ArcGIS Knowledge enterprise knowledge graph, the analyst: Conducts spatial movement analyses on phone call GPS pings Leverages spatial relationships in link analyses connecting multiple persons of interest Creates a static report of findings to hand off to other stakeholders Ukraine Common Intelligence Picture From Esri Defense and Intelligence Forum (3min 30sec) The war in Ukraine requires maintaining operational awareness at all times is critical. In this demo, Jessica Johnson uses ArcGIS Knowledge to fuse order of battle information with open source intelligence in the spatially intelligent ArcGIS, giving allies the Common Intelligence Picture they need. Integrating tracked battle units and equipment with news reports of attacks provides analysts with full context quickly and uses graph analytics to identify the most important units of interest to focus on.  Technical Sessions These User Conference recordings are also now available in the Esri Media website.

With knowledge graph support in the ArcGIS API for Python, and the guides and sample notebooks below, data scientists, engineers, and developers can easily: Get started working with ArcGIS Knowledge graphs using the arcgis.graph module Create new knowledge graphs with sample data Back up existing knowledge graphs and support ArcGIS Enterprise migrations Automate the data hydration of your enterprise knowledge graph This post will be periodically updated with additional resource links related to Python. Be sure to check out other developer resources for JavaScript and Knowledge Server REST API.  Starting with the Python version (2.1.0.3), the native version in the ArcGIS Pro 3.2 release, you can also use local ArcGIS Notebooks inside Pro and the ArcGIS API for Python version out of the box to create and work with Knowledge Graphs with ArcGIS Knowledge in Enterprise 11.1 or higher. You can also easily share those Pro projects with other analysts.  These python guides will help you get started: Introduction and Creating a knowledge graph: https://developers.arcgis.com/python/guide/part1-introduction-to-knowledge-graphs/ Writing to a knowledge graphs (Apply Edits): https://developers.arcgis.com/python/guide/part3-edit-knowledge-graph/ Reading knowledge graphs (Search & Query): https://developers.arcgis.com/python/guide/part2-search-query-knowledge-graph/ Sample notebooks: Note to python beginners: you don't need to know any python to run these, simply replace a few ArcGIS login values in the first cells of these notebooks. Create a sample knowledge graph with dataset pulled from a web API: With 'DataLoadingBees' notebook (attached below), you can pull bee observation data collected by users of the iNaturalist application. This sample data model and queries is also used in other training resources, demos, JavaScript developer resources. The workflow is simple: Provide portal credentials (publisher or admin), a name for your graph, and the number of observations you want to get (up to 200, due to API limits). Run all cells Get a graph that contains observations (only those that are licensed as public domain, so all this data can be used in demos without worry), users, and species with their relationships. There is a data model for this drawn out in the notebook but it can also be easily seen when you start exploring the data.  Never lose your graphs again with backups! Create a backup of an ArcGIS Knowledge graph you have created to store your data model and data. The backup will be in the format of JSON files that can read to recreate your graph or be shared for others to be able to create the same graph on a different server. Create and load knowledge graph backups Sample notebooks with a Pro Project: ArcGIS Dependencies: This sample ArcGIS Pro project can be used for quickly creating a knowledge graph, or an entity-relationship network, representing the IT infrastructure and content from one or more ArcGIS Enterprise or ArcGIS Online portals using a graph database in ArcGIS Enterprise with ArcGIS Knowledge.

Update: 6/24/2025 Five publicly available code samples are now available for key ArcGIS Knowledge classes and methods within the Maps SDK for JavaScript in the ArcGIS Developer site. These samples also provide 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:   NEW! Web Link Charts and link chart layer: create a web link chart, a new core view, from a link chart layer, a composite layer which operates very similar to how a knowledge graph layer works in a map view. https://developers.arcgis.com/javascript/latest/sample-code/linkchart/  Leverage the beta Link Chart web component as well! Watch this demo to see how this can be combined with map interactions in a custom application! 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/ 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 check out this 2024 Developer Summit technical development session walking through some of the basics, and start in the documentation for the core concepts here: Introduction to Knowledge Graph. NEW in Q2 2025! Now Supporting Knowledge graph data model editing In JavaScript 4.33, we have added data model editing support for knowledge graph services. You can now add, update and delete entity types and relationship types from your knowledge graph. You can also add, update and delete the properties for those entity and relationship types, as well as the field indexes and the knowledge graph search index. Introducing Web Link Charts We are excited to announce the release of web link charts in Maps SDK for JavaScript 4.32 out of beta! Web link charts contain a link chart layer with the data from your knowledge graph and are loaded in a link chart view. Web link charts are a new core view (like MapView and SceneView) that are specifically for visually representing and analyzing all or part of a knowledge graph. For those familiar with web maps in teh JS SDK, the analagous components for Link Charts are: Map -> WebLinkChart View -> LinkChartView KnowledgeGraphLayer -> LinkChartLayer  Web Link Charts are built on the same core technology as a Map that allows you to leverage existing tools and patterns, like symbology for each layer, while also adding some additional link chart specific capabilities for refining your link chart visualizations and conducting graph analysis. Layouts: Apply different layouts to provide different visualizations to better understand the patterns in your data. For example, geographic layout arranges spatial entities using their geometry with their connected nonspatial data clustered around them while chronological layout arranges entities and relationships according to time. Expand: Finds and adds all directly connected entities "one-hop" away from the given entities and adds the entities and their connecting relationships to the link chart. Connect: Adds direct relationships between the given entities to the link chart. Add and Remove Records: Update the data in your link chart by adding or removing entities and relationships. Link charts also have a new web component for easily displaying a link chart from a portal content item with a layout switcher, handling all the rendering with default layout settings.

Updated April 20, 2023 Summary Current ArcGIS Knowledge users, please coordinate with your GIS Administrators before upgrading to ArcGIS Pro 3.1, ArcGIS API for Python 2.1.0, or the ArcGIS Maps SDK for JavaScript 4.26. These releases are incompatible with earlier versions of ArcGIS Knowledge server in ArcGIS Enterprise (10.9.1, 11.0). Changes in the ArcGIS Knowledge service released in ArcGIS Enterprise 11.1, April 20, 2023, will also create services that are incompatible with earlier versions of these ArcGIS applications and developer clients in custom development projects. See graphic below for summary. Notice to ArcGIS Pro Users: ArcGIS Knowledge desktop users should not download ArcGIS Pro 3.1 until their GIS Administrators upgrade the existing ArcGIS Knowledge servers to ArcGIS Server v11.1, which were released April 20, 2023. Please coordinate your upgrade needs with your ArcGIS Enterprise Administrator.  Notice to ArcGIS Administrators: Please coordinate with ArcGIS Knowledge users and developers before upgrading to ArcGIS Enterprise 11.1 to prevent any disruption in work.   Notice to Developers and Data Scientists: This ArcGIS Knowledge service update in Enterprise 11.1 will custom development projects (or plans for custom development) that leverage the ArcGIS Knowledge REST API, the ArcGIS API for Python, or the Maps SDK for JavaScript. For JavaScript apps, the upgrade should not require coding changes, but version upgrades will need to be coordinated. For Python notebooks and scripts, existing scripts should continue to returns results, however the format of the results may differ with 11.1 services and require changes.   What is happening?  In order for ArcGIS Knowledge applications to support existing data in supported User Managed NoSQL Data Stores, e.g. Neo4j graph databases, the ArcGIS Knowledge services specification in ArcGIS Enterprise 11.1 will change such that earlier ArcGIS Pro versions prior Pro 3.1 will not be able to connect with the new ArcGIS Knowledge Graph services. Similarly, Knowledge functionality in ArcGIS Pro 3.1 will not be able to save new work with older versions of ArcGIS Knowledge services (in Enterprise 10.9.1 or 11.0).  How will it impact different Knowledge users?  For ArcGIS Knowledge Pro users, nothing needs to be done immediately. However, ArcGIS Knowledge users should NOT download ArcGIS Pro 3.1 at their primary workstation when it becomes available. It will not be compatible with existing ArcGIS Knowledge services. When the organization GIS Administrator upgrades their ArcGIS Knowledge Server to ArcGIS Enterprise 11.1, users can then download ArcGIS Pro 3.1 or a later version, and save their existing ArcGIS Pro projects that include Knowledge investigations within the new Pro 3.1 user interface. If your organization remains on ArcGIS Enterprise 10.9.1 or 11.0, users will NOT be able to upgrade to Pro 3.1 and continue to save work on existing ArcGIS Knowledge investigations.  ArcGIS Enterprise administrators using ArcGIS Knowledge in Enterprise 10.9.1 or 11.0 will follow the normal Enterprise Server Upgrade pattern. Administrators should work with users of ArcGIS Knowledge to plan the timing of their Pro and Enterprise upgrades to ensure no disruption of work.  For enterprise developers, this functional change is considered a breaking change in the ArcGIS Knowledge REST API design. If your organization has built or is considering building a custom web application or data pipeline application directly using the ArcGIS Knowledge REST API between now and when your organization upgrades to ArcGIS Enterprise 11.1, your application will require some migration planning and re-engineering effort at the time your organization upgrades its Knowledge Graph Services to ArcGIS Enterprise 11.1. Custom applications using the JavaScript API should not be affected. Code examples leveraging the REST API in 11.0 vs 11.1 will be developed to support this transition.   Why the change?  ArcGIS Knowledge enables analysts in organizations to connect, analyze and visualize large amounts of disparate data together as enterprise knowledge graphs.  Some organizations have already invested in modeling, organizing and storing connected data in existing graph databases (e.g. Neo4j) or multi-model databases with graph support (e.g. Amazon Neptune, Microsoft Azure CosmosDB).  With ArcGIS Enterprise 11.1, ArcGIS Knowledge will support Neo4j Enterprise Edition as Esri’s first supported NoSQL Data Store with user managed data. This breaking change enables critical changes that allows organizations to leverage data stores with user managed data without needing to manage that data using ArcGIS exclusively. ArcGIS is an open and interoperable system, allowing customers to own their data pipelines. ArcGIS intends to connect directly to more third party, user-managed graph and multi-model data stores in order to help enterprises combine the power of spatial and graph analytics while leveraging their existing IT architecture investments. In order to enable ArcGIS applications and developer tools to leverage these user-managed graph data more seamlessly, the product team needed to implement a new, more flexible engineering pattern within the Knowledge graph service. This technology change, unfortunately, is not backwards compatible with previous versions of the service.   Summary of ArcGIS Knowledge Product Version Compatibility (Server/Client)  If you have further questions, please comment on this blog and we will do our best to answer. We apologize for any confusion or inconvenience these changes may cause, but are confident that ArcGIS will be much stronger and more flexible to meet enterprise needs going forward. Thank you! ...
