Languages Overview

XSMP Modeler uses several related languages, each with a focused role.

At a glance

Language	File	Main purpose
Project	xsmp.project	Define project sources, dependencies, tools and profiles
Catalogue	.xsmpcat	Define types, interfaces, models and services
Configuration	.xsmpcfg	Provide reusable configuration values
Assembly	.xsmpasb	Instantiate systems and connect local configuration
Link base	.xsmplnk	Declare reusable connections
Schedule	.xsmpsed	Declare tasks, events and task activities

In addition to native XSMP source files, the same project source folders can contain SMP XML source files such as .smpcat, .smpcfg, .smplnk, .smpasb, and .smpsed. When they appear in a declared source folder, XSMP Modeler imports them automatically and treats them as project modeling sources.

Typical progression

Most projects are built in this order:

1. xsmp.project
2. .xsmpcat
3. .xsmpcfg
4. .xsmpasb
5. .xsmplnk
6. .xsmpsed

You do not need every language in every project, but this order matches how systems usually grow.

Relationship between the languages

• xsmp.project selects the workspace context.
• .xsmpcat defines the reusable types and components.
• .xsmpcfg applies values to component structures.
• .xsmpasb instantiates components and sub-assemblies.
• .xsmplnk collects reusable connections.
• .xsmpsed drives execution and orchestration.

Shared syntax

Several languages share common syntax for:

• paths
• template parameters
• placeholders
• values

See Paths, Templates and Values for the common rules.
