Grakn Workbase 1.2.5

Documentation: https://dev.grakn.ai/docs/workbase/overview

Distribution

Grakn Workbase is available for Linux, Mac and Windows (download binaries below).

For Mac, Grakn Workbase also available through Brew Cask:

brew tap graknlabs/tap
brew cask install graknlabs/tap/grakn-workbase

New Features

• Visualising only the most granular role when loading roleplayers.
  When the Load Roleplayers is switched on in the Settings, the visualised role edges no longer include the roles that are played by the roleplayer indirectly (via role hierarchies). Instead, the only role edge that is visualised belongs to the most granular role played by that roleplayer.

• Avoid visualising edges where their from and to nodes are not present in the visualiser.
  Previously, when constructing edges for a given node, all possible edges from that node were constructed regardless of whether the destination node was present in the visualiser. This is no longer the case and edges are only constructed and visualised between the given node and the nodes that are to be produced as a result of the given query.

Bugs Fixed

• Individual nodes are again draggable after shift + double-clicking on a node.
  As a result of a recent bug, the dragging behaviour would break when the rendered nodes were added to the visualiser by shift + double-clicking on a node (loading its attributes). This unexpected behaviour has been fixed.

• The right-bar is now scrollable.
  The right-bar in the Visualiser and Schema Designer now becomes scrollable as its height exceeds the maximum height of the main window.

• Double-clicking a relation node loads its neighbours when Load Roleplayers setting is switched on.
  Loading a relation's neighbours now works as expected regardless of the Load Roleplayers status in the settings.

Code Refactors

• The logic for loading neighbours has been moved to the Canvas Data Builder.
  As a continuation of a previous refactors, all logic related to loading neighbours of different node types has now been moved, along with its unit tests, to the Canvas Data Builder module.

• Performing the assembling and testing for windows to a CircleCI Windows machine.
  All CI tasks, including those for Windows, now take place on CircleCI machines.

Grakn Workbase 1.2.4

Documentation: https://dev.grakn.ai/docs/workbase/overview

Distribution

Grakn Workbase is available for Linux, Mac and Windows (download binaries below).

For Mac, Grakn Workbase also available through Brew Cask:

brew tap graknlabs/tap
brew tap-pin graknlabs/tap
brew cask install grakn-workbase

Bugs Fixed

• In the Schema Designer, an edge between a relation and its roleplayer is displayed once.
  Duplicated edges between a relation type and its roleplayer types are now removed.

• Inferred concept may now be explained again.
  As a result of a recent bug, attempting to explain an inferred concept would throw an error. This bug is now fixed and inferred concepts ma now be explained again.

• Deselecting a node hides the labels on edges connected to that node.
  As a result of a recent bug, edge labels would continue to show after the connected node was deselected. The bug is now fixed and deleting a node behaves as expected.

• Individual nodes are again draggable after loading neighbours of a given node.
  As a result of a recent bug, the dragging behaviour would break when the rendered nodes were added to the visualiser by double-clicking on a node (loading neighbours). This unexpected behaviour has been fixed and dragging individual nodes is again possible regardless of how they have been added to the visualiser.

Grakn Workbase 1.2.3

Documentation: https://dev.grakn.ai/docs/workbase/overview

Distribution

Grakn Workbase is available for Linux, Mac and Windows (download binaries below).

For Mac, Grakn Workbase is also available through Brew Cask:

brew tap graknlabs/tap
brew tap-pin graknlabs/tap
brew cask install grakn-workbase

New Features

When querying for concept types or visualising a schema in the Schema Designer, labels and arrows are now always displayed on the edges.

Bugs Fixed

• Support for Grakn KGMS 1.5.8
  Grakn Workbase can now be used with Grakn KGMS 1.5.8 via a secured connection.

• Visualiser now supports running queries that retrieve concepts types from the schema.
  The visualiser can now be used to query the entire or a subset of the schema, reliably.

• A human-readable error message is displayed when attempting to run an unsupported query.
  Users are now presented with a user-friendly message when attempting to run a query that is currently unsupported by Grakn Workbase, as opposed to displaying a syntax error.

• No longer checks for the existence of instances when un-hasing an attribute from a concept type.
  Removing the association between a concept type and attribute type can be done regardless of whether or not the attribute type has any instances. This check has now been removed from the Schema Designer.

• Requires the completion of a running process before allowing the user to clear the graph or switch keyspaces.
  To avoid rendering nodes and edges on the wrong canvas, while a query is still running, users are now presented with a message requiring them to wait for the current process to complete, when they attempt to switch keyspaces or clear the canvas.

Code Refactors

• The logic used in building the canvas nodes and edges from Graql answers are now unified.
  For the purpose of reducing complexity, the logic in producing nodes and edges based on a given concept or answer is now unified within one module.

• The end-to-end tests are rewritten to produce a more reliable test suit
  The end-to-end tests are now deterministic and easier to extend, maintain and reuse.

Grakn Workbase 1.2.0

Documentation: https://dev.grakn.ai/docs/workbase/overview

Distribution

Now officially available for 3 OSs: Linux, Mac and Windows (see binaries below). For Mac, grakn-workbase is also available through Brew Cask:

brew tap graknlabs/tap
brew tap-pin graknlabs/tap
brew cask install grakn-workbase

Architecture

The grakn-workbase module now has its own repository (hit star on graknlabs/grakn-workbase!). This allows us to iterate on grakn-workbase more flexibly, independent of grakn-core.

Visualisation

• Introduced a the shortcut cmd + g to clear the graph.
• Better graph design, animation and layout algorithm, as well as smoother click, select and drag UX.
• Visualiser footer displays metrics of graph canvas.
• Inference explanation behaves accurately for patterns with conjunction, relations and attributes.
• Double clicking on a concept now also retrieves inferred neighbours.

Grakn Workbase 1.1.1

Dear Grakn Community,

As most of you are aware of, we recently released Workbase 1.1.0 which now enables support for Grakn KGMS. However, there was a bug in the connection and authentication gateway. This PATCH RELEASE, Workbase 1.1.1, fixes this issue.

You can find out more about the 1.1.0 from the Workbase 1.1.0 release notes.

Enjoy the new Grakn Workbase 1.1.1 with Grakn KGMS on Google Cloud and Amazon AWS! We look forward to hearing your feedback!

Grakn Workbase 1.1.0 (please use 1.1.1)

Dear Grakn Community, Grakn Workbase 1.1.0 has finally been unleashed, and it now works with Grakn KGMS on Google Cloud and Amazon AWS!

As always, thank you so much to everyone in the community for helping us improve Grakn, and in this case, Workbase. And well done to our Grakn Warriors! :)

Architecture Refactor and KGMS Authentication

In this release, we redesigned the Workbase architecture and increased the test coverage, which we believe should increase the robustness and reliability of the codebase and the user experience. This refactor also included enabling Grakn Workbase to work with Grakn KGMS in the cloud. Grakn Workbase now starts with a page where the user can choose to connect to either Grakn Core or KGMS, and provide their login details when using KGMS.

Improvements on the Visualiser: features and bug fixes

1. We have introduced visualiser tabs! In the visualiser page, you can now create multiple tabs to visualise multiple queries at the same time. The tabs may also be configured to connect to different keyspaces. The tabs will maintain the state of each query and visualisation.
2. The visualiser can now visualise schema concepts. You just need to write Graql queries to query schema concepts!
3. We added a footer bar to show additional details, such as the number of entities, attributes and relationships shown in the graph. We will continue to show additional details of the visualisation on this footer bar.
4. Improved the fluid motion function of the graph. The graph should have a better "groove" to it now ;)
5. Added a relationships panel to the right bar, to show details about a relationship concept.
6. Added a system preferences panel to configure:
   • the connection to Grakn database server
   • to manage keyspaces: view, add and delete keyspaces
7. We also added a few more keyboard shortcuts for common tasks:
   • cmd + g : clear the graph
   • cmd + = : zoom-in for the whole application window
   • cmd + - : zoom-in for the whole application window
8. General bug fixes:
   • Fixed backtracking of a regex during query parsing
   • Click-and-holding a node no longer multi-selects the nodes
   • Information in the identity and attributes panel in the right bar are now correctly saved when minimised
   • Rapid answer explanation requests are now handled correctly in the in the transaction connection to Grakn.
   • Answer explanations now properly handle explanations with conjunctions.

Introducing the Schema Designer!

It's still early days for the schema designer, but we're excited to share this as a tool that will help everyone model their schema better and easier.

At the moment, the Schema Designer includes the following capabilities:

1. Define entity types
2. Define attribute types
3. Define relationship types
4. Define rules; but you will still have to write the when and then patterns using Graql
5. List attribute types that schema concept has
6. Add attribute types to existing schema concept types
7. Remove attribute types to existing schema concept types
8. Delete schema concepts through a context menu
9. Toggle the visibility of nodes of a given type (Entity, Attribute, Relationship) through a display settings

That's it! Download Workbase from the list of binaries below. We hope you enjoy the new Workbase and connect it to your Grakn KGMS on Google or AWS!

Given that this is just the beginning for Grakn Workbase, we'd really love to hear your feedback on what you like, what don't like, as well as what you wish it had!

Grakn Workbase 1.0.0

This release was initially part of Grakn Core 1.4 release on 24 Sep 2018. It is migrated to this repository, as Grakn Workbase will have its own dedicated repository going forward.

Finally, Workbase is born into this world!

Our beloved Grakn Community, Grakn Workbase 1.0 is finally released! (Compatible with Grakn Core 1.4.0 onwards)

Well done to our Grakn Warriors (kuple!) and, as always, thank you so much to our amazing community for helping us improve Grakn every day of the journey!

There has been a lot of work put into our new "Knowledge IDE" - starting with the visualiser. Why? Performance and usability! This first release is already available for Linux, Mac and Windows. You can download it directly from the list of binaries below (the download centre page for Workbase will be updated to make the following binaries available too).
