Overview
This release features architectural changes that strengthen the power and performance of Tom Sawyer Perspectives. The integrators for Amazon Neptune, Microsoft Azure Cosmos DB, Neo4j, OrientDB, and Apache TinkerPop can now automatically bind query results to elements in the model. This lets you visualize and explore the data in a graph database without having to create a schema or manually define the data bindings. The new native graph in-memory model supports more effective interaction with graph databases that matches the structure of the data. The model includes fast access to related model elements without the need for lookup functions, and provides a greatly simplified way to create a drawing view from your data without the need to manually define IDs for edges' end nodes.
The new interactive schema editor allows Designer users to easily view and update the schema for Perspectives applications and supports both vertex and edge element types. The improved support for schema inheritance includes generalization, multiple inheritance, and redefinition. There is also a new schema code generator that can take a schema as input and generate a Java domain object model to support faster creation of custom application code.
The in-memory model itself has become more powerful with additional support for vertex and edge types, Reactive Streams for events, stream traversals, native support for graphs, model evaluation functions to perform operations on the native graph model, and serialization in both JSON-LD and BSON. And there is a new TSModel REST view for improved interoperability between Perspectives server-side components and other Tom Sawyer Software or third-party components. All these additions make it faster and easier to get a new Perspectives application up and running.
In the Designer, when adding a graph, analyzer, or view, the user now selects the relevant domains—collections of model elements with filter-style conditions—and adds actions to the domain rules. In the drawing view, disconnected nodes can be sorted by name and there is improved routing for intergraph edges. When defining an inspector view, a user can choose to include attributes dynamically at run time, explicitly select from the schema-defined attributes, or do a combination of both.
In Business Process, rich text documents as well as links to file paths and URLs can be attached to process tasks in the Execution module. Also, users can now retrieve the direct URL of process instances for easier sharing.
New
Integrators
Added support for the creation of vertex and edge element types in the model
Added support for automatic bindings, which allows users to visualize and explore data in a graph database without having to create a schema or manually define the data bindings. This allows new applications to be built very quickly
Added support for Swagger 2.0 in schema extraction for the REST integrator
Added support for changing the target graph in the RDF integrator
Schema
Added new graph schema editor, which replaces the previous schema editor view
Added schema code generator, which creates Java domain object model classes as output code for a provided schema
Model
Added support for a native graph in-memory model
Added support for Reactive Streams event subscriptions
Added support for JSON-LD serialization of the model
Added support for BSON serialization of the model
Added model evaluation functions to perform operations on the native graph model
Added automatically created, universally unique ID to each model element, which can be used in views with the $id() function
Designer
Added the Domain concept, which allows the Designer user to define flexible sets of elements that can be used in graph, analyzer, and view definitions
Views
Drawing
Added ability to sort disconnected nodes by name
Inspector
Added support for a dynamic inspector, which can show attributes of an element determined at run time
REST
Added the REST view, which allows the Designer user to define a RESTful web service against the model

Issues
Uninstalling or reinstalling Tom Sawyer Perspectives removes all files from the installation directories, even those created after the initial installation. Therefore, we do not recommend storing any additional files in the installation directories.
There is an issue using the default configuration for the https protocol with the Neo4j integrator. Contact Support for assistance in using this configuration.
Use of OpenJDK 11 can cause issues with multiline, vertical, and diagonal edge labels in desktop applications on Windows. This issue does not occur when Tom Sawyer Perspectives is used with OpenJDK 15.
