GEXF Format

Description​

GEXF (Graph Exchange XML Format) is an XML graph format popularized by Gephi for dynamic and attributed networks. IterableData reads GEXF via NetworkX and yields node records first, then edge records. It is read-only in this release.

File Extensions​

  • .gexf — Graph Exchange XML Format

Implementation Details​

Reading​

  • Parses with networkx.read_gexf
  • Converts to node then edge dicts (same shape as GraphML)
  • Node: {"_type": "node", "id": "...", ...}
  • Edge: {"_type": "edge", "source": "...", "target": "...", ...}

Writing​

Writing is not supported.

Key Features​

  • Gephi-friendly: common interchange for network tools
  • Attributed nodes/edges: attributes appear on records
  • Shared record model with GraphML and DOT

Usage​

from iterable import open_iterable

with open_iterable("network.gexf") as source:
    for row in source:
        print(row["_type"], row)

Parameters​

No format-specific iterableargs.

Installation​

pip install 'iterabledata[graph]'

Requires networkx.

Limitations​

  1. Read-only
  2. Memory: entire graph loaded before iteration
  3. Requires networkx
  4. Dynamic GEXF timelines may be simplified by the NetworkX reader

Error Handling​

  • ImportError: missing networkx — install iterabledata[graph]
  • Parse / I/O errors: invalid GEXF or missing files
  • Format is registered writable=False
