Site Log Manager (SLM) The Site Log Manager (SLM) is a web framework for managing GNSS ground station meta data. SLM is maintained by the International GNSS Service and is freely licensed for general use under the MIT License. The SLM is implemented in Python and JavaScript using the Django web framework.

The SLM aims to provide:

• GNSS Site meta data (site log) management with a moderation workflow.
• Support for multiple organizations and networks to be managed in an access controlled way.
• Full legacy site log format support (both import and export).
• Full GeodesyML support (both import and export).
• JSON renderings of meta data.
• Point-and-click graphical editing of site log data.
• Public RESTful api for searching site log data.
• Authenticated RESTful api for updating site log data.
• Full access to the historical record.
• Visualizations of networks and site information.
• Configurable data validation that goes above and beyond schema validation.
• Image and file attachments to sites.
• A no-fork extensible architecture that allows organizations to modify out-of-the box behavior with plugins.

Full documentation is available on igs-slm.readthedocs.org and speaks to multiple audiences:

• Developers will want to refer to the Installation, Architecture, Commands and Reference sections.
• System administrators may be interested in operations and Commands.
• Users and network coordinators will be interested in the User Manual.
• Developers wishing to work with SLM managed data will be interested in the APIs.
• Everyone, but particularly program managers will want to take a look at the Overview.

⚠️ Warning

The SLM has reached beta-maturity but is still undergoing rapid development. Check back soon for new documentation and updates. A version 1.0 stable release is expected in late September 2024.
