arcgis-dependency-mapper

You can map dependencies between ArcGIS Online web maps, layers, and dashboards by analyzing item data with the ArcGIS Python API to extract relationships and build a navigable dependency graph. This reveals how items interconnect.

The best way to perform impact analysis before deleting an ArcGIS Online layer is to generate a dependency graph that traces references from web maps, dashboards, and Experience Builder apps back to that resource, showing exactly what would break.

Yes, you can audit ArcGIS item usage at scale by running the dependency mapper against root items. It parses maps, dashboards, and experiences to produce human- and machine-readable reports for governance and inventory.

Dependency extraction for ArcGIS Online items works by relying on the ArcGIS Python API to parse item data, identify how web maps depend on layers, and extract how apps reference those maps or layers to support safe modifications.

Yes, you need the ArcGIS Python API to extract dependency relationships from web maps. The skill relies on this API to parse item data and build a navigable graph showing connections between layers, maps, and apps.

A limitation of using a dependency graph for GIS project audits is that it operates across maps, dashboards, and experiences, meaning dependencies outside these specific ArcGIS item types may not be captured in the navigable graph.
