LutaML is a data model accessor that supports various data model formats.
This plugin allows you to access the following types of information models from within a Metanorma document:
-
EXPRESS (
*.exp
files) -
LutaML-UML (
*.lutaml
files) -
Enterprise Architect exported UML in XMI format (
*.xmi
files)
The LutaML plugin supports working with EXPRESS schema files to render EXPRESS models and definitions.
LutaML supports accessing EXPRESS models via the Expressir parser.
This attribute allows specifying one or more EXPRESS files to defined names
for later use with lutaml_express
command.
Syntax:
:lutaml-express-index: shortname_of_index; name_of_schemas_listing_file.yml;
Where:
shortname_of_index
-
is name of the parsed EXPRESS files context for the later use.
name_of_schemas_listing_file.yml
-
location of the YAML index file to parse all EXPRESS files listed within.
lutaml_express
command:lutaml-express-index: my_custom_name; /path/to/schemas.yml
[lutaml_express,my_custom_name,context]
----
{% for schema in context.schemas %}
== {{schema.id}}
{% for entity in schema.entities %}
=== {{entity.id}}
{% endfor %}
{% endfor %}
Where the schemas.yml
file contains:
---
schemas:
action_schema:
path: "../../schemas/resources/action_schema/action_schema.exp"
application_context_schema:
path: "../../schemas/resources/application_context_schema/application_context_schema.exp"
The schemas listing file is a YAML file that lists all EXPRESS files to be parsed. The file should have the following structure:
---
schemas:
schema_name:
path: path/to/schema_file.exp
schema_name_2:
path: path/to/schema_file_2.exp
Where:
schema_name
-
is the name of the EXPRESS schema.
path
-
(optional) path to the EXPRESS schema file. When the path is not specified, the command will look for the schema file in the directory where the YAML file is located using the filename pattern
{schema_name}.exp
. The path can be relative to the YAML file or an absolute path.
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_express
block:
[lutaml_express,example.exp,my_context]
----
{% for schema in my_context.schemas %}
== {{schema.id}}
{% for entity in schema.entities %}
=== {{entity.id}}
{% endfor %}
{% endfor %}
----
Note
|
The lutaml command can auto-detect the EXPRESS schema file type by the
file extension. If the file extension is .exp , the command will use the
Expressir parser to parse the file. If the file extension is .lutaml , the
command will use the Lutaml parser to parse the file.
|
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.adoc
file 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.exp
file can be accessed with.
Will produce this output:
== test_schema
=== my_type1 === my_type2 === my_type3 === my_type4 === my_type5
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.
Syntax:
: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 command
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 %}
----
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. |
The LutaML plugin supports working with LutaML UML files to render UML diagrams and class definitions.
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
}
}
}
....
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.identifier
Value type and multiplicity
String [1]
==== concepts
Concepts.
Table 2. Specification of Register.concepts
Value type and multiplicity
Concepts [0..*]
The command accepts two options:
skip_headers=true
-
(or just
skip_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 of2
means 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 of2
will have the "Attributes" section at depth3
.
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
command:
[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
CharacterString
imlicistAttributeProfile
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
The LutaML plugin supports working with Enterprise Architect exported XMI files to render UML diagrams and class definitions.
The commands are prefixed as lutaml_ea_*
to denote their specific use with
Enterprise Architect XMI files.
This attribute allows specifying one or more XMI files to defined names
for later use with lutaml_ea_*
commands.
Syntax:
:lutaml-xmi-index: index_name; index_path[; config=config_path]
where:
index_name
-
name of index
index_path
-
path to XMI file for the later use with
lutaml_ea_*
command config_path
-
optional, location of YAML configuration file that specifies what packages to include in the render, what render style is desired and location of the root package.
lutaml_ea_xmi
command:lutaml-xmi-index: first-xmi-index; /path/to/first.xmi
:lutaml-xmi-index: second-xmi-index; /path/to/second.xmi; config=/path/to/config.yml
[lutaml_ea_xmi,index=first-xmi-index]
--
...
--
lutaml_ea_diagram::[name="NameOfDiagramInSecondXmiIndex",base_path="./xmi-images",format="png",index="second-xmi-index"]
...
The command lutaml_ea_xmi
will load the XMI file from the path
/path/to/first.xmi
which is specified by the index
: first-xmi-index
.
The command lutaml_ea_diagram
will load the XMI file from the path
/path/to/second.xmi
which is specified by the index
: second-xmi-index
.
This command allows to quickly render a LutaML diagram as an image file by specifying the name of diagram.
Syntax:
lutaml_ea_diagram::[{options}]
where {options}
is a hash of options, where:
name
-
(mandatory) name of the diagram to render.
base_path
-
(mandatory) base path where the diagram images are located.
format
-
(optional) format of the image file. Defaults to
png
. index
-
(optional) index name of the XMI file. If the index is not provided, the command will look for the diagram in the first XMI file specified through the
lutaml_ea_xmi
command. package
-
(optional) name of the package which contains the diagram. If the package is not provided, the command will look for the diagram across all packages in the XMI file.
The diagram with name name_of_diagram
will be converted into the following
Metanorma block:
[[figure-{{ diagram.xmi_id }}]]
.{{ diagram.name }}
image::{{ image_base_path }}/{{ diagram.xmi_id }}.{{ format | default: 'png' }}[]
lutaml_ea_diagram::[name="name_of_diagram",base_path="/path/to/xmi-images",format="png"]
Renders the diagram with name name_of_diagram
from the XMI file in PNG format,
where the EA images exported with the XMI file are at /path/to/xmi-images
.
lutaml_ea_diagram::[name="DiagramName",package="PackageA",base_path="/path/to/xmi-images"]
The search wil be restricted to the diagrams named DiagramName
in the
PackageA
package.
:lutaml-xmi-index: index_name; /path/to/xmi-file.xmi
...
lutaml_ea_diagram::[name="name_of_diagram",base_path="/path/to/xmi-images",format="png",index="index_name"]
Renders the diagram with name name_of_diagram
from the XMI file in PNG format,
where the EA images exported with the XMI file are at /path/to/xmi-images
and
the XMI file defined in the index index_name
.
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.xmi
specifies the path of xmi file. -
name
option only,name
option withpackage
option orpath
option. 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 byname
option) inside thepackage
(specified bypackage
option). Thepackage
option must be used with thename
option. (e.g.package="uro",name="_BoundarySurface"
) -
path="PathOfClass"
specifies theabsolute
path of theclass
which is started with::
(e.g.path="::EA_Model::Conceptual Models::i-UR::Urban Planning ADE 3. 1::uro::_BoundarySurface"
) orrelative
path of theclass
which 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.liquid
defined inlib/metanorma/plugin/lutaml/templates
. This template can be customized by changing the template path in thetemplate
option. -
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
.
The lutaml_ea_xmi
command supersedes the lutaml_uml_datamodel_description
command which it is functionally equivalent to.
This command renders data model packages and its dependent objects for supplied XMI file, by using Liquid Drop objects.
Note
|
The performance of lutaml_ea_xmi exceeds
lutaml_uml_datamodel_description by 10~20 times (Tested with a 10.6MB XMI file
with 120,000+ lines).
|
Note
|
To migrate to this command from lutaml_uml_datamodel_description , just
replace the command 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"
The guidance file should be in the following format:
---
classes:
- name: "NameOfClass"
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
.
The name
of class can be defined in the following ways:
-
name: "NameOfClass"
specifies the name of theclass
. (e.g.name: "Building"
) If there are multiple classes with the same name, it is recommended to specify the class by absolute path. -
name: "::NameOfPackage::NameOfClass"
specifies the name of theclass
inabsolute
path. (e.g.name: "::EA_Model::Conceptual Models::CityGML2.0::bldg::Building"
)
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
command can be used:
[lutaml_uml_datamodel_description, path/to/example.xmi]
--
[.before]
....
my text
....
[.diagram_include_block, base_path="requirements/", format="emf"]
....

....
--
--
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 command will overwrite text, not thatliteral
block 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 command will overwrite text -
[.after, package="Another"]
- block text to be inserted before(after in case of.before
name) the package -
[.package_text, position="after", package="Another"]
- include custom adoc code into package rendered body,position
is 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_path
is a required attribute to supply path prefix where to look for a diagram image.format
is 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 command 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"]
- command to include files (.adoc
or.liquid
) for each package name. Attributebase_path
is a required attribute to supply path prefix where to look for file to include. command will look for a file calledbase_path
+/
package_name
(downcase, replace : → '', ' ' → '') +.adoc
[.liquid
], eg for package 'My Package name' andbase_path
eq tomy/path
, command 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 commandses 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 command when document rendered lutaml_uml_datamodel_description
command as it needs diagram lookup table in order to reference package diagram.
Will produce this output:

=== Additional Information
text after CityGML package
In addition to the XMI file, this command 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_depth
equal to2
tells 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_depth
equal 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 command:
[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.
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.xml
specifies 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=dict
define the context in the template.
