Purpose
LutaML is a data model accessor that supports various data model formats, including:
-
EXPRESS (
*.expfiles) -
OMG UML in XMI format (
*.xmifiles)
This plugin allows you to access LutaML models from within a Metanorma document.
Installation
$ gem install metanorma-plugin-lutaml
Usage with EXPRESS
General
LutaML supports accessing EXPRESS models via the Expressir parser.
Usage of the lutaml command
Given an example.exp EXPRESS file with content:
SCHEMA test_schema 'test';
(* Need select elements for measure_value *)
REFERENCE FROM measure_schema
(measure_value);
TYPE my_type1 = EXTENSIBLE SELECT;
END_TYPE;
TYPE my_type2 = EXTENSIBLE ENUMERATION;
END_TYPE;
TYPE my_type3 = EXTENSIBLE ENUMERATION;
END_TYPE;
TYPE my_type4 = EXTENSIBLE ENUMERATION;
END_TYPE;
TYPE my_type5 = EXTENSIBLE ENUMERATION;
END_TYPE;
END_SCHEMA;
And the lutaml block:
[lutaml,example.exp,my_context]
----
{% for schema in my_context.schemas %}
== {{schema.id}}
{% for entity in schema.entities %}
=== {{entity.id}}
{% endfor %}
{% endfor %}
----
Where:
-
content within the block is called the “template”;
-
{example.exp}is the location of the EXPRESS schema file (*.exp) that contains data to be loaded. Location of the file is computed relative to the source directory that[lutaml]is used (e.g., if[lutaml,example.exp,my_context]is invoked in an.adocfile located at/foo/bar/doc.adoc, the data file is expected to be found at/foo/bar/example.exp); -
{my_context}is the name where the EXPRESS Repository read from the.expfile can be accessed with.
Will produce this output:
== test_schema
=== my_type1 === my_type2 === my_type3 === my_type4 === my_type5
This command also supports .lutaml files.
Instead of using the direct path to the file one can use lutaml-express-index
document attribute to supply directory with express files or YAML index file to
parse as well as the cache file location.
The syntax is as follows:
:lutaml-express-index: my_custom_name; dir_or_index_path[; cache=cache_path]
Where:
-
my_custom_name- is name of the parsed EXPRESS files context for the later use with lutaml macro -
dir_or_index_path- location of directory with EXPRESS files or path to the YAML index file to parse -
cache_path- optional, location of the Expressir cache file to use
Example of usage:
= Document title
Author
:lutaml-express-index: index_name; /path/to/express_files; cache=/path/to/cache_file.yaml
[lutaml,index_name,context]
----
{% for schema in context.schemas %}
== {{schema.id}}
{% endfor %}
----
Using config.yaml
This functionality allows [lutaml_express] blocks to load a full set of
EXPRESS schemas in one index, and then provide a select ("filter") option
per-block via a separate YAML file.
:lutaml-express-index: all_schemas; ../schemas_all.yaml;
[lutaml_express,all_schemas,context,leveloffset=+1,config_yaml=schemas.yaml]
---
{% assign selected = context.schemas | where: "selected" %}
{% render "templates/resources/schema" for selected as schema %}
---
Where schemas_all.yml provides all schemas:
---
schemas:
action_schema:
path: "../../schemas/resources/action_schema/action_schema.exp"
application_context_schema:
path: "../../schemas/resources/application_context_schema/application_context_schema.exp"
approval_schema:
path: "../../schemas/resources/approval_schema/approval_schema.exp"
...
And schemas.yaml only selects 2 schemas:
---
schemas:
action_schema:
anything: ...
application_context_schema:
anything: ...
The resulting block adds the select attribute to every schema of the the
"context" object, which allows you to filter those out for complex operations
via Liquid:
[lutaml_express,schemas_1,repo,leveloffset=+1,config_yaml=select.yaml]
---
{% assign selected = repo.schemas | where: "selected" %}
... do things with `selected` ...
|
Note
|
This functionality is used in the ISO 10303 SRL to load the full schema set at once but only render the selected schemas in individual documents. |
Usage with UML
Rendering a LutaML view: lutaml_diagram
This command allows to quickly render a LutaML view as an image file.
Given a file example.lutaml file with content:
diagram MyView {
title "my diagram"
enum AddressClassProfile {
imlicistAttributeProfile: CharacterString [0..1] {
definition
this is multiline with `asciidoc`
end definition
}
}
class AttributeProfile {
+addressClassProfile: CharacterString [0..1]
imlicistAttributeProfile: CharacterString [0..1] {
definition this is attribute definition
}
}
}
The lutaml_diagram command will add the image to the document.
lutaml_diagram::example.lutaml[]
The lutaml_diagram command can also be used to denote a block with an embedded
LutaML view.
For example:
[lutaml_diagram]
....
diagram MyView {
title "my diagram"
enum AddressClassProfile {
imlicistAttributeProfile: CharacterString [0..1] {
definition {
This is multiline AsciiDoc content.
}
}
}
class AttributeProfile {
+addressClassProfile: CharacterString [0..1]
imlicistAttributeProfile: CharacterString [0..1] {
definition this is attribute definition
}
}
}
....
Rendering a LutaML Enterprise Architect diagram from XMI: lutaml_ea_diagram
This command allows to quickly render a LutaML diagram as an image file by specifying the name of diagram.
lutaml_ea_diagram::[name="name_of_diagram",base_path="/path/to/xmi-images",format="png"]
The code will search the diagram with name name_of_diagram and then
render it as:
[[figure-{{ diagram.xmi_id }}]]
.{{ diagram.name }}
image::{{ image_base_path }}/{{ diagram.xmi_id }}.{{ format | default: 'png' }}[]
Rendering a LutaML GML Dictionary: lutaml_gml_dictionary
This command allows to render a LutaML GML Dictionary by using Liquid Drop.
GmlDictionaryDrop has the following attributes:
-
name
-
file_name
-
dictionary_entry
Each dictionary_entry has the following attributes:
-
name
-
description
lutaml_gml_dictionary::/path/to/dictionary.xml[template="/path/to/template.liquid",context=dict]
The command accepts the options listed below:
-
/path/to/dictionary.xmlspecifies the path of xml file of the GML Dictionary. -
template="/path/to/template.liquid"specifies the liquid template. For example, you can create a liquid template and link it bytemplate. -
context=dictdefine the context in the template.
[cols="3a,22a"]
|===
| Name | {{ dict.file_name }}
h| Code h| Description
{% for entry in dict.dictionary_entry %}
| {{ entry.name }} | {{ entry.description }}
{% endfor %}
|===
[.source]
<<source_link>>
In spite of specifying the path of the template, you can also define an inline
template within a block by
[lutaml_gml_dictionary,"/path/to/dictionary.xml",context=dict].
[lutaml_gml_dictionary,"/path/to/dictionary.xml",context=dict]
--
{% capture link %}https://www.test.com/{{ dict.file_name }}{% endcapture %}
[cols="3a,22a"]
|===
| File Name | {{ dict.file_name }}
h| URL | {{ link }}
h| Help | Description
{% for entry in dict.dictionary_entry %}
| {{ entry.name }} | {{ entry.description }}
{% endfor %}
|===
[.source]
<<source_link>>

Rendering a LutaML table of a class: lutaml_klass_table
This command allows to render a LutaML table of a class by using Liquid Drop.
The table will show:
-
Class Name
-
Class Definition
-
Inherited Properties
-
Self-defined Properties
-
Properties Inherited from Association
-
Properties Defined in Association
lutaml_klass_table::/path/to/example.xmi[name="NameOfClass",template="/path/to/templates/_my_klass_table.liquid"]
The command accepts the options listed below:
-
/path/to/example.xmispecifies the path of xmi file. -
nameoption only,nameoption withpackageoption orpathoption. One of 3 forms of options can be used to specify the name of the class.-
name="NameOfClass"specifies the name of theclass. (e.g.name="Building") If there are multiple classes with the same name, other form of options are recommended to specify the class. -
package="NameOfPackage"name="NameOfClass"specifies the name of theclass(specified bynameoption) inside thepackage(specified bypackageoption). Thepackageoption must be used with thenameoption. (e.g.package="uro",name="_BoundarySurface") -
path="PathOfClass"specifies theabsolutepath of theclasswhich is started with::(e.g.path="::EA_Model::Conceptual Models::i-UR::Urban Planning ADE 3. 1::uro::_BoundarySurface") orrelativepath of theclasswhich is not started with::(e.g.path="uro::_BoundarySurface"). The last part of the path separated by::is the name of theclass. The other parts of the path are the names of thepackages.
-
-
template="/path/to/templates/_my_klass_table.liquid"specifies the path of the liquid template. (Optional) By default, it will look for the template_klass_table.liquiddefined inlib/metanorma/plugin/lutaml/templates. This template can be customized by changing the template path in thetemplateoption. -
guidance="/path/to/my_guidance.yml"specifies the path of the yaml file of the guidance. (Optional)
The guidance file should be in the following format:
---
classes:
- name: Name Of Class
attributes:
- name: Name Of Attribute (e.g. gml:boundedBy)
used: false
guidance: |
Drop guidance message here.
...
If you want to define the guidance, you can define the name of the class
under classes. Then define which attributes you want to add guidance by the
name. Set used to show the attribute is used or not. Drop the message of
guidance in guidance.
Generating UML class and attributes: lutaml_uml_class
This command allows rendering a definition clause for a UML class.
Given example.lutaml with this content:
class Register {
definition {
A register of information.
}
identifier: String[1] {
definition {
Unique identifier of the register.
}
}
concepts: Concept[0..*] {
definition {
Concepts.
}
}
}
The command:
[lutaml_uml_class,views/Register_Register.lutaml,Register]
Will produce this output:
== Register
A register of information.
=== Attributes
==== identifier
Unique identifier of the register.
Table 1. Specification of Register.identifierValue type and multiplicity
String [1]==== concepts
Concepts.
Table 2. Specification of Register.conceptsValue type and multiplicity
Concepts [0..*]
The command accepts two options:
-
skip_headers=true(or justskip_headers). The initial heading (the UML class name) will not be generated. This is useful if additional content is to be supplied to the clause, such as diagrams that are defined outside the UML model. -
depth={n}. (default:2) This determines the depth of the generated headings. A depth of2means the initial heading will have 2 equal signs, and so forth. The heading depth of the attributes are in relation to the initial depth, so a depth of2will have the "Attributes" section at depth3.
lutaml_uml_attributes_table
This command allows rendering definition tables for a UML model.
Given example.lutaml file with the content:
diagram MyView {
title "my diagram"
enum AddressClassProfile {
imlicistAttributeProfile: CharacterString [0..1] {
definition
this is multiline with `ascidoc`
end definition
}
}
class AttributeProfile {
+addressClassProfile: CharacterString [0..1]
imlicistAttributeProfile: CharacterString [0..1] {
definition this is attribute definition
}
}
}
And the lutaml_uml_attributes_table macro:
[lutaml_uml_attributes_table, example.lutaml, AttributeProfile]
Will produce this output:
=== AttributeProfile
Table 3. AttributeProfile attributes Name Definition Mandatory/ Optional/ Conditional Max Occur Data Type addressClassProfile
TODO: enum’s definition
M
1
CharacterStringimlicistAttributeProfile
this is attribute definition with multiply lines
M
1
CharacterString
In case of "enumeration" (AddressClassProfile) entity:
[lutaml_uml_attributes_table, example.lutaml, AddressClassProfile]
Will produce this output:
=== AddressClassProfile
Table 4. AddressClassProfile values Name Definition imlicistAttributeProfile
this is multiline with
asciidoc
Usage of lutaml_uml_datamodel_description macro
This command allows to quickly render data model packages and its dependent objects for supplied XMI file.
Given an Enterprise Architect example.xmi file with 2 packages:
-
'Another'
-
'CityGML'
The lutaml_uml_datamodel_description macro can be used:
[lutaml_uml_datamodel_description, path/to/example.xmi]
--
[.before]
....
my text
....
[.diagram_include_block, base_path="requirements/", format="emf"]
....
Diagram text
....
[.include_block, package="Another", base_path="spec/fixtures"]
....
my text
....
[.include_block, base_path="spec/fixtures"]
....
my text
....
[.before, package="Another"]
....
text before Another package
....
[.after, package="Another"]
....
text after Another package
....
[.after, package="CityGML"]
....
text after CityGML package
....
[.after]
....
footer text
....
--
--
Where:
-
path/to/example.xmi- required, path to the XMI file to render -
[.before]- block text that adds additional text before the rendered output, can be used only once, additional occurrences of macro will overwrite text, not thatliteralblock style must be used in there(eg….) -
[.after]- block text that adds additional text after the rendered output, can be used only once, additional occurrences of macro will overwrite text -
[.after, package="Another"]- block text to be inserted before(after in case of.beforename) the package -
[.package_text, position="after", package="Another"]- include custom adoc code into package rendered body,positionis a a required attribute which tells where to insert the code. -
[.package_text, package="Another"]- same as above, but include block will be included only for supplied package name -
[.diagram_include_block]- block text to automatically include diagram images. Attributebase_pathis a required attribute to supply path prefix where to look for a diagram image.formatis an optional attribute that tells what file extension to use when including diagram file.The logic is as follows:
{% for diagram in package.diagrams %}
[[figure-{{ diagram.xmi_id }}]]
.{{ diagram.name }}
image::{{ image_base_path }}/{{ diagram.xmi_id }}.{{ format | default: 'png' }}[]
{% if diagram.definition %}
{{ diagram.definition | html2adoc }}
{% endif %}
{% endfor %}
For instance, the script will take package diagrams supplied in the XMI file and will try to include image with the name equal to diagram' xmi_id attribute plus .png. Also one can add any text to the macro text, it will be added as paragraph before each image include.
-
[.diagram_include_block, package="Another"]- same as above, but diagram will be included only for supplied package name -
[.include_block, base_path="spec/fixtures"]- macro to include files (.adocor.liquid) for each package name. Attributebase_pathis a required attribute to supply path prefix where to look for file to include. Macro will look for a file calledbase_path+/package_name(downcase, replace : → '', ' ' → '') +.adoc[.liquid], eg for package 'My Package name' andbase_patheq tomy/path, macro will look for the following file path:my/path/_my_package_name.adoc. -
[.include_block, package="Another", base_path="spec/fixtures"]- same as above, but include block will be included only for supplied package name
|
Note
|
.after, .before, package_text and include_block macroses all can be used with additional option - liquid, if this option is supplied then the code inside block will be interpolated in liquid context
|
There are two other commands that are used to refer to LutaML generated document elements:
-
lutaml_figure. Provides a reference anchor to a figure defined in the XMI file, using its XMI ID for reference. -
lutaml_table. Provides a reference anchor to the definition tables of a particular package, class, enumeration or data type object in the XMI.
The syntax is as follows:
// For lutaml_figure
This is lutaml_figure::[package="Wrapper root package", name="Fig B1 Full model"] figure
// For lutaml_table
This is lutaml_table::[package="Wrapper root package"] package
This is lutaml_table::[package="Wrapper root package", class="my name"] class
This is lutaml_table::[package="Wrapper root package", enum="my name"] enumeration
This is lutaml_table::[package="Wrapper root package", data_type="my name"] data type
This code will be transformed into [figure-{diagram.xmi_id}] and will point to diagram figure. One can only use this macro when document rendered lutaml_uml_datamodel_description macro as it needs diagram lookup table in order to reference package diagram.
Will produce this output:
my text

=== Additional Information
text after CityGML package
In addition to the XMI file, this macro also supports a YAML configuration file that specifies:
-
What packages to include in the render;
-
What render style is desired;
-
Location of the root package (which package should the iterative process start at).
The format for using the YAML configuration file:
---
packages:
# includes these packages
- "Package *"
- two*
- three
# skips these packages
- skip: four
render_style: entity_list | data_dictionary | default
section_depth: 2
Where:
-
packages- required, root element with the list of strings or objects -
Package *- pattern matching, specifies lookup condition for packages to render.NoteIn this example, it is equal to the following regular expression: /^Package.*$/ -
skip: four- object with package name to skip -
render_style- what template to use to render packages, can be one of:-
entity_list -
data_dictionary; or -
default
-
-
section_depth- what package to use as root package for render. e.g., asection_depthequal to2tells the processor to use the first nested package of the first root packages in XMI file.EXAMPLE: If the XMI file has this package structure, and we have
section_depthequal to 2, root package will beone-1.[ { name: 'One', packages: [{ name: 'one-1' }, { name: 'one-2' }] }, { name: 'Two', packages: [{ name: 'two-1' }, { name: 'two-2' }] } ]
Usage with macro:
[lutaml_uml_datamodel_description, path/to/example.xmi, path/to/config.yml]
----
[.diagram_include_block, base_path="models/Images", format="png"]
...
...
----
The processor will read the supplied YAML config file (path/to/config.yml),
and iterate through packages according to the order supplied in the file. All
packages that matches skip in the YAML config file will be skipped during
render.
Usage of lutaml_ea_xmi macro
This command is a replacement for lutaml_uml_datamodel_description to perform
the same functionalities of lutaml_uml_datamodel_description, which is to
render data model packages and its dependent objects for supplied XMI file, by
using Liquid Drop. The performance of lutaml_ea_xmi can be improved by
10~20 times. (Tested with a 10.6MB XMI file with 120000+ lines)
To use this macro, you only need to replace lutaml_uml_datamodel_description
by lutaml_ea_xmi.
Replace:
[lutaml_uml_datamodel_description, path/to/example.xmi]
...
By:
[lutaml_ea_xmi, path/to/example.xmi]
...
You can define guidance in the configuration file as well. The configuration file will looks like:
packages:
- my_package
guidance: "path/to/guidance.yaml"
Please refer to lutaml_klass_table section for how to configure the guidance
yaml file.
