Graph Metrics

The web viewer exposes RDF knowledge-graph metrics for each file and for the combined graph. Metrics include graph size, predicate and class usage, connectivity, datatype distribution, label coverage, and external namespace usage.

Combined metrics skip exact largest-distance computation for large resource networks and show this explicitly on the metrics page.

The same metrics are available from Python:

import h5rdmtoolbox as h5tbx

metrics = h5tbx.compute_metrics("example.h5")

with h5tbx.File("example.h5") as h5:
    metrics = h5.metrics()
