  • Updated dependencies.

[1.22.1] - 2024-11-06

Changed

  • Updated from_grip and to_grip following changes in GRIP. GRIP is project management software used by Rijkswaterstaat, the executive branch of the Dutch Ministry of Infrastructure and Water management.

[1.22.0] - 2024-09-24

Added

[1.21.1] - 2024-05-31

Added

[1.21.0] - 2024-04-29

Added

  • Added a Convention enumeration for the ragraph.io.matrix functions and friends as well as in the plot module.
  • For the methods on Graph instances it's available as a convention keyword such as on get_adjacency_matrix.
  • You can supply the convention to ragraph.plot.Style.convention.
  • Note that all analysis algorithms and metrics are left untouched and as such the matrices used during these analyses will still be in the original IR-FAD convention (inputs in rows, feedback above diagonal).
  • Objecttype import in ragraph.io.grip.

Changed

  • The default Canopy export type has been set to a "graph" from now on.

[1.20.3] - 2023-11-21

Changed

  • Updated dependency constraints.

[1.20.2] - 2023-10-02

Fixed

  • Also improve resilience of CSV imports, since CSV exports now support 'empty' weights. This makes for better round-tripping I/O when using CSV.

[1.20.1] - 2023-10-02

Added

  • Truck Steering System dataset for the DSM conference 2023.

Fixed

  • Improved resilience of the CSV I/O module.

[1.20.0] - 2023-09-19

Added

  • Graph export functionality in ragraph.io.grip for facilitating a GRIP round trip for Rijkswaterstaat.

Fixed

  • Graph import functionality for the GRIP exports from Rijkswaterstaat in ragraph.io.grip such that dependencies between functions and requirements are included..

[1.19.5] - 2023-08-16

Fixed

  • Harden more plotting methods that depend on the length or index of things that might be empty.

[1.19.4] - 2023-08-16

Fixed

  • Provided all min() and max() calls with a default value where there was an iterable as an argument.
  • Fixed a line in XML I/O that directly compared a type(v) == str instead of the recommended isinstance(v, str).

[1.19.3] - 2023-08-15

Fixed

  • Handling an edge case where the Labels plot component would return an error if it was created with an empty list.

[1.19.2] - 2023-07-06

Changed

  • Added an __all__ = [...] entry to ragraph.plot that includes Style so that it's clearer that it can be imported there.
  • Changed the default for the reference documentation generation for private module contents (function/classes). The ragraph.analysis module overrides this by including their private methods such that tinkerers have full interactive documentation there.

[1.19.1] - 2023-07-06

Changed

  • Switched documentation from Sphinx to MkDocs. A lot of docstrings were impacted, but code should still run fine with minor adjustments, if any at all. Docs should now be way better to navigate over at https://ragraph.ratio-case.nl.

[1.19.0] - 2023-05-24

Changed

  • Changed the way one does sigma and delta MDM analysis. These are now offered in simpler, functional methods as opposed to the relatively heavy class approach that was taken before. We chose for only a minor version increment as this is a rather niche part of our public methods, of which a clear example is now included in the comparison section.

[1.18.0] - 2023-05-12

Added

  • Graph import functionality for the GRIP exports from Rijkswaterstaat in ragraph.io.grip.

[1.17.1] - 2023-04-05

Fixed

  • Minor tweaks and fixes for formatting.
  • Added ruff formatting config.

[1.17.0] - 2023-02-17

Added

  • Genetic sequencing of node sequences built on ratio-genetic-py. See ragraph.analysis.sequence.genetic and ragraph.analysis.sequence._genetic.genetic_sequencing for more info.

[1.16.1] - 2022-10-27

Added

  • A convenient all extra to install all extras at once.

[1.16.0] - 2022-07-27

Added

  • Ways to highlight rows and/or columns in all PieMap plots. See highlighting in the usage documentation.

[1.15.1] - 2022-06-14

Added

  • Added an option to the ragraph.analysis.compatibility.CompatibilityAnalysis interface_compatibilitythat toggles whether interface checking should be a prerequisite for checking compatibility. The default is the current behavior (True), where compatibility is only checked for direct variant interfaces. Any two variants without a direct interface is then assumed to be compatible. Toggling that to False implies that any two variants should be compatible, regardless of the existence of an interface.

[1.15.0] - 2022-06-08

Added

Fixed

  • Fixed duplicate UUID field in Metadata.

1.14.2

  • Hotfix to scaling.

1.14.1

  • Added an extra scaling_weight field to the ragraph.plot.generic.PieMapStyle object that scales the piecharts drawn in a piemap plot component according to a specified edge weight. Note that it stacks with every edge in a bundle between two displayed nodes by means of the product of the available values.

1.14.0

  • Added ragraph.analysis.comparison.DeltaAnalysis class for performing delta analysis on Graph objects.
  • Added ragraph.analysis.comparison.SigmaAnalysis class for performing sigma analysis on Graph objects.

1.13.1

  • Switch from a brute-force to a Binary Decision Diagram implementation as the backbone for the compatibility module.

1.13.0

1.12.1

1.12.0

  • Updated and reorganized all dependencies into a more simplified structure.
  • Now, the only optional dependencies are RaESL (as extra esl) and kaleido (as extra plot).
  • Removed the obsolete API server with Connexion. It's currently unused and only burdens the package with higher maintenance.
  • If we'd ever need it again, we can look back at it later in the Git history.
  • Connexion's development is currently changing a lot as well, so we'd probably be better off starting over then.
  • Removed CLI as the only supported command was the API server.

1.11.4

  • Fixup Canopy export schema key for "session" format.

1.11.3

  • Fixup the export of labels in Canopy (de-duplicate, keep order).

1.11.2

  • Fixup the export of weights in Canopy (force floats).

1.11.1

  • Fixup the $schema key in Canopy export.

1.11.0

  • Added methods to import and export graphs from and to https://canopy.ratio-case.nl and its corresponding JSON schemas: ragraph.io.canopy.from_canopy and ragraph.io.canopy.to_canopy.

1.10.6

  • Allow specification of a symmetrize parameter to the different Markov clustering algorithms that adds the transpose of a (potentially asymmetrical) matrix to create a guaranteed symmetrical matrix with respect to the diagonal. This should give more consistent clustering results while maintaining "stronger" connections between nodes that already had bi-directional edges between them. Influences ragraph.analysis.cluster.markov, ragraph.analysis.cluster.hierarchical_markov, and ragraph.analysis.heuristics.markov_gamma. The Markov sequencing is not included, as that would not make sense at all.
  • Modified Markov sequencing with a scale toggle that modifies the inflow vector to contain the sum of the corresponding adjacency matrix's columns. To interpret this in a sequencing context: a node doesn't have to "split" its output and divide it over it's successors, but it rather delivers something that each target node should acquire fully. It is therefore the new default option (scale = True). Clustering algorithms have not been adjusted to incorporate this as that would stray too far off the original Markov clustering implementation.
  • Added rudimentary debugging output to analysis. The output is rather verbose and is sent on a ragraph.analysis.logger named "ragraph.analysis".

1.10.5

  • Tiny bugfix when axis sort should neither sort by width or bus status (only hierarchy).

1.10.4

1.10.3

1.10.2

  • Add inherit and loops boolean toggles to any applicable Analysis class and therefore to all methods where applicable.

1.10.1

  • Add an inherit option to the SCC algorithm. By default, it is set to True and makes sure any edges between descendants are taken into account, too.

1.10.0

  • Added better control of the default sorting behavior in RaGraph MDM plots. See axis_sort.
  • Updated documentation to reflect color overrides plotting.
  • Improved graph slicing to include edge filtering or leaving everything blank for a full deepcopy. See ragraph.graph.Graph.get_graph_slice.

1.9.0

  • Allow combined color palette overrides, e.g. both a categorical color override for a field as well as a numerical color palette.

1.8.9

  • Add a SCC tearing sequencing algorithm. See scc_tearing for usage.

1.8.8

1.8.7

  • Fixup a plotting issue where subplots didn't receive the plotting style options.

1.8.6

  • Fixup a pre-processing step in branchsort analyses where root lists of length 1 were treated as cases where nothing had to be sorted.

1.8.4

  • Add option to allow CORS.

1.8.3

1.8.2

1.8.1

  • Refactor ragraph.plot.colors into ragraph.colors. This allows it to be used even if the plotting dependencies aren't present.

1.8.0

  • Initial merge of API v2.

1.7.4

  • Added more DSM datasets.

1.7.3

  • Pipeline and versioning updates.

1.7.2

  • Dependency updates.

1.7.1

1.7.0

  • Addition of the ragraph.plot.dmm plot function for visualizing mapping matrices.
  • Addition of the row_col_numbers argument to the ragraph.plot.mdm and ragraph.plot.dsm plot functions for adding row and column numbers to the figures.

1.6.1

  • Several small bug fixes regarding the scaling of figures when adding custom plot components.
  • Added usage docs for ragraph.plot over at plotting.

1.6.0

  • Added a ragraph.analysis.sequence.axis sequencing 'algorithm' that sorts nodes like we typically want them to on matrix axis as a replacement for the utils floating around. That means, they get sorted by node kind first (and hierarchy) primarily, followed by a sorting of "sibling" nodes where buses and larger clusters (in terms of displayed leaf nodes) are put first.

1.5.0

  • Added UUID generation to the ragraph.generic.Metadata class. This means that we tag every ragraph.node.Node, ragraph.edge.Edge, or ragraph.graph.Graph instance with a unique code to track them over time. This is especially useful for the API and future referencing of identical objects.
  • This change affects the .json_dict property of these objects to work with these UUIDs (as strings) instead of the object names to reference them.
  • UUIDs are now generated as an incrementing integer during test runs such that we generate the same identical (and easily identifiable) in each run. Note that they are very much random in "real-life" situations.
  • Removed soon-to-be-deprecated API v1 tests as bringing them up-to-par would be a waste of time.

1.4.5

  • Improved scaling of large MDM plots.

1.4.4

  • Bug fix. ragraph.plot.mdm now supports plotting graphs with more than ten edge labels out of the box.
  • Bug fix. ragraph.plot.mdm legend plotting no longer crashes on empty list of edges.

1.4.3

  • Some convenience fixups to the ragraph.api module.
  • The CLI now supports arguments via environment variables. They are of the form of RAGRAPH_{COMMAND}_{OPTION}.

1.4.2

  • Bug fix of ragraph.plot.components.piemap.PieMap regarding the visualization of matrices that contain one or more busareas.
  • Additon of the sort keyword to ragraph.plot.mdm which defines whether the provided leaf list should be sorted according to the hierarchical node structure and different node domains. Defaults to True.
  • Changed the default value of the keyword show of ragraph.plot.mdm to False.

1.4.1

  • Bug fix. The type of ragraph.plot.generic.Palettes.fields is updated to Dict[str, Union[str, List[str]]]. As such, one can providing a mapping of field names to a hex-colorcodes or to a lists of hex-colorcodes:

  • A single colorcode is to be used when one wants to set the color of an edge label.

  • A list of colorcodes is to be used when one wants to provide a colormap for an edge weight.

1.4.0

  • Added a rudimentary plotting module under ragraph.plot. The only currently built-in plot type is the ragraph.plot.mdm, but groundwork is in place with re-usable plot components under ragraph.plot.components and the color palette management under ragraph.plot.colors. The usage manual should follow soon.

1.3.2

1.3.1

  • Fixed an issue where the ruamel.yaml dependency is installed as ruamel_yaml.

1.3.0

1.2.2

1.2.1

  • Added ragraph.graph.Graph.get_edge_selection and ragraph.graph.Graph.get_node_and_edge_selection methods to select nodes and edges for plotting purposes.

1.2.0

  • Added a ragraph.generic.Mapping class that will mainly be featured in future endeavours featuring plotting functionality. Works as a dictionary whose keys are also properties of the object. Moreover, you can include default values and optional validators for certain keys/properties of the object. It's intended as a base class to derive mappings from for a specific purpose.

1.1.0

  • Simplified the use of the ragraph.analysis._classes.Analysis classes and their corresponding wrappers by moving the latter into the former. The publicly available methods are now the wrapped ones that check the parameter input.

1.0.1

  • Added better analysis descriptions through their repr and str representations. For help regarding an analysis, simply look at its repr or string how to call it.
  • Made branchsort more convenient by allowing supplying Analysis instances, too.

1.0.0

  • Apply new Python project template.
  • Set algorithm specific modules as private modules. Regular usage should refer to the category specific imported ones. This means that from ragraph.analyis.bus import gamma from now on undeniably imports the function and not the submodule (which is now named ragraph.analysis.bus._gamma.)

0.3.1

  • Fix the Climate Control case to correspond to the reference document by Pimmler. Make sure to use it with an edge weight filter set to "adjacency" for algorithms that require nonnegative input.
  • Tests are updated accordingly and an additional test checks whether relevant datasets are actually symmetric.

0.3.0

  • More sophisticated Archimate3.0 export via an archimate dictionary in our Annotations object. You can now set the element type and documentation of each element using Annotations.archimate["type"] and Annotations.archimate["documentation"]. For all possible types, please refer to https://www.opengroup.org/xsd/archimate.

0.2.0

0.1.2

  • Fixed loading JSON files with set edge IDs. It now sets the last used edge ID number correctly.

0.1.1

  • Minor bug fix for edge ID generation.

0.1.0

  • Added XML I/O support using the XML Metadata Interchange format (XMI) in ragraph.io.xml.

0.0.1

Initial version from preceding projects graph_io, graph_analysis, ratio_datasets, architecture and ratio_backend.
