MG-SOFT YANG Explorer Professional Edition

Product History

This page provides information about the major new features introduced in the latest as well as in the past releases of MG-SOFT YANG Explorer Professional Edition.

What's New in MG-SOFT YANG Explorer Pro., Version 4

 Complete YANG 1.1 Support.
In addition to the original YANG data modeling language version 1 (RFC6020), MG-SOFT YANG Explorer now fully supports also the new YANG version 1.1 (RFC7950). The software's GUI has been extended and the built- in YANG validation engine has been rewritten to fully support all YANG 1.1 syntax and semantics, including the new statements ('action', 'anydata'), new 'XPath' functions, modified rules for 'notifications', changed lexical rules and the new submodule scoping rules, to name some of the more important changes in YANG 1.1. The software now lets you load any set of valid YANG 1.1 and YANG 1 modules (as well as YIN 1.1. and YIN 1 modules).
 Extended NETCONF Content Editor with complete support for YANG 1.1.
The built-in DSDL schema generator and the NETCONF validation engine have been extended and re-written to provide full support for YANG 1.1 (in addition to YANG 1). NETCONF Content Editor and Validator lets you easily compose or load any type of NETCONF XML instance document (e.g., edit- config, get-config, rpc, rpc-reply, etc.) and validate it using the DSDL schemas, which are automatically generated from selected YANG 1.1 and YANG 1 modules. This enables you to validate if the actual content (payload) of NETCONF requests, responses and notifications comply with definitions in the selected YANG modules.
 Extended UML Class Diagram module with support for YANG 1.1.
The UML Class Diagram feature has been revised and extended to enable visualizing also YANG 1.1 modules in form of a UML (Unified Modeling Language) class diagram.
 GUI enhancements and improvements and initial HiDPI support.
A number of GUI enhancements and improvements have been implemented in order to make the application even more intuitive and user-friendly. Furthermore, the entire GUI has been revised to properly support large font sizes in order to make the application text easily readable also on modern high pixel density displays (e.g., 4K/UHD). The application text scales properly with the system scaling setting on Windows and one can further tweak the appearance of the text and tables by using several startup parameters.
 Updated and enhanced documentation.
Updated and enhanced user manual and product documentation with numerous hints and usage examples will help you get the most from MG-SOFT YANG Explorer Pro.
 Besides, a number of minor improvements have been implemented and all known problems occurring in older versions have been fixed for this release.

What's New in MG-SOFT YANG Explorer Pro., Version 3

 Significantly Enhanced NETCONF Content Editor.
In addition to the built-in full-fledged XML Editor, NETCONF Content Editor now supports also visual editing of XML documents. Simply right-click a node in the tree view and add/remove elements and set their values by choosing commands from the context menu. This feature is DSDL schema aware and will allow adding only constructs that are defined in enabled YANG modules.
Furthermore, the new quick options panel for edit-config now lets you specify the most common options (target configuration, default operations, test options, error options) by simply selecting the desired entries from drop-down menus and checkboxes.
 UML Class Diagrams.
MG-SOFT YANG Explorer can now visualize the selected YANG modules in form of a UML (Unified Modeling Language) class diagram. UML class diagram displays different types of YANG nodes as classes, with their attributes, methods and relationships (e.g., dependency, composition, inheritance, etc.). You can explore the classes and their relationships either within the scope of a single or several associated YANG modules. Furthermore, YANG Explorer lets you focus on the desired elements of YANG modules by specifying excludes (excluding specific, user-selected classes) and by setting various display options (to toggle displaying certain types of classes globally, etc.). You can zoom in and out of the UML class diagram, pan the diagram, reposition classes and connections in the diagram, print the diagram to a printer and save it as an image file for external use.
 Exploring Cross-References in YANG Modules
(Find Usages, Go to Definition, Find Leafrefs, Find Leafref References, Go to Target, etc.).

YANG Explorer now implements a wealth of new features that let you effectively explore references between YANG statements within one or more YANG modules and submodules. While exploring YANG modules, it is vital to be able to quickly navigate between a reference of a definition and the definition itself, for example, to be able to select an "if-feature" statement and quickly locate the definition of a matching "feature" statement. YANG Explorer now offers such navigation whenever a reference exists. The software also provides a reverse functionality that lets you quickly find all usages of a definition in the loaded YANG/YIN modules, for example, to find all "if-features" that reference a specific "feature" definition. This is supported for "typedef", "grouping", "identity", "feature" and "extension" statements. 'Leafrefs' (YANG statements with the "leafref" type) are also an important concept in YANG, and the software now offers a quick way to find all 'leafrefs' and their target schema nodes in a module. Furthermore, you can also select any "leaf" or "leaf-list" node in the YANG tree and search for 'leafrefs' that reference it by using the "Find Referencing Leafrefs" functionality.
 Source File View.
Besides displaying YANG or YIN modules' contents in a visual manner, where module elements are represented in a hierarchical tree structure, YANG Explorer now also features a view that displays the content of the YANG source file (i.e., YANG code). You can click any node or sub-node in the YANG Tree panel to view the corresponding section of the YANG source file that defines the node/statement. In addition, the built-in Find toolbar lets you quickly find a specified text phrase in the YANG source file.
 Textual Data Tree View.
Since YANG may be quite complex to read and understand, it is useful to examine the data tree defined by YANG statements in form of a concise textual tree. YANG Explorer now provides this functionality by utilizing the notation which is often used in IETF discussions and publications. The contents of this view changes with current selection in the YANG Tree, so you can quickly obtain the textual tree representation of an arbitrary data tree branch.
 Extended and Improved Find Nodes Functionality.
The Find Nodes feature now lets you search through all loaded YANG/YIN modules for nodes of a specific type (e.g., a "container" or "leaf" or "description" or "config" or "base", etc.). Furthermore, you can combine the regular text search condition with the node type search condition in order to find a (sub)node of a certain type, whose argument contains a user-specified string.
 Updated and Enhanced User Manual.
The bundled user manual has been significanlty revised and extended with numerous hints and usage examples that will help you get the most from MG-SOFT YANG Explorer Pro.
 Besides, a number of minor improvements have been implemented and all known problems occurring in older versions have been fixed for this release.
