Local Web Viewer

Local Web Viewer#

Start the linked-data web viewer with h5tbx serve:

h5tbx serve example.h5
h5tbx serve data/ --h5ext=.h5 --h5ext=.hdf5
h5tbx serve example.h5 --file-uri https://doi.org/10.5281/zenodo.17572275# --local-iri-pattern "https://doi.org/10.5281/zenodo.*"

If no filename is provided, h5tbx serve lists matching files in the current directory. Each file page links to RDF serializations, an interactive graph, SPARQL queries, graph metrics, and SHACL validation.

Graph View#

The graph page can be shown as a 2D or 3D graph. Nodes are draggable and can be expanded, hidden, and restored. Literal values are shown in popovers.

Use the graph controls to tune the visualization:

  • Color nodes by RDF class or namespace.

  • Select a light or strong color scheme.

  • Change node size and edge width.

  • Set the graph background color.

  • Limit large graphs with detail presets, node and edge limits, and search.

The same controls are available for the combined graph. The combined graph contains all served files and enrichment graphs loaded while browsing.

RDF Responses#

HDF5 object URLs such as /example.h5/group/dataset are dereferenceable RDF resources. Browsers get an HTML representation by default; clients can request RDF with Accept: text/turtle or Accept: application/ld+json. The format query parameter overrides content negotiation, for example ?format=ttl, ?format=jsonld, ?format=nt, ?format=xml, or ?format=html.
