All about PGML Files

The PGML file type is primarily associated with ArgoUML.

PGML	File extension: PGML
	File type:	UML diagram file

What is a PGML file?

PGML files mostly belong to ArgoUML. PGML files store UML diagrams for use with ArgoUML. They are written in an XML format that holds the diagram structure, including classes, relationships, and layout details.
Using this text-based format means you can open them in any text editor, but for accurate viewing and editing, use ArgoUML.

Function: Save and represent UML design data.

Operation: Use XML tags to define each diagram element.

Viewing: Best interpreted through specialized UML software like ArgoUML.

How to open a PGML file

You need a suitable software like ArgoUML to open a PGML file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PGML file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PGML file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert PGML files:

ArgoUML
See the previous paragraphs to learn more about the main application. PGML files are often referred to as ArgoUML developers because this type of file is primarily created or used by this software.
Precision Graphics Markup Language
Precision Graphics Markup Language (PGML) is an XML-based language for representing vector graphics. It was a W3C submission, but was not adopted as a recommendation. PGML and VML, another XML-based vector graphics language, were later joined and improved upon to create SVG. The identifying characters used for this association are - Hex: 3C 3F 78 6D 6C 20 76 65 72 73 69 6F 6E 3D 22 31 2E 30 22, ASCII: <?xml version="1.0". This file format is classified as XML.

PGML file format:

If you know the file format, you can also find out how to open or edit the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the PGML files:

PGML is seldom used as a file extension and is primarily used by a single program. However, the following two file formats are common:

90% of all PGML files are Precision Graphics Markup Language files, which are based on the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The files are on average 26 KB in size and range from 250 bytes to 86 KB. The file type is old but is used even today. The files contain the following words: <!DOCTYPE pgml SYSTEM "pgml.dtd">, <?xml version="1.0" encoding="UTF-8" ?>, argouml, diagram, pgml description, UMLClassDiagram and static_structure. A usual file name is umlexamplesv2_ClassDiagram7.pgml. These files are often associated with diagram, class, case, sequence, model, data, diagrammedeclasses, umlexamples and common.

The remaining 10% of all PGML files are different files with different signatures. Sometimes used for state. You can get all the details of your PGML file by dragging it onto this page or by clicking the button "Choose your .pgml file to view" above.

How to solve problems with PGML files

Associate the PGML file extension with the correct application.
Update your software that should actually open uml diagram files. Because only the current version supports the latest PGML file format. Search, therefore, e.g. on the manufacturer website after an available ArgoUML update.
To make sure that your PGML file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
