 Graph Docker environment
 ========================
 
 Build
 -----
 
 .. code:: bash
 
     $ git clone https://forge.softwareheritage.org/source/swh-graph.git
     $ cd swh-graph
     $ docker build --tag swh-graph dockerfiles
 
 Run
 ---
 
 Given a graph specified by:
 
 - ``g.edges.csv.gz``: gzip-compressed csv file with one edge per line, as a
   "SRC_ID SPACE DST_ID" string, where identifiers are the `persistent identifier
   <https://docs.softwareheritage.org/devel/swh-model/persistent-identifiers.html#persistent-identifiers>`_
   of each node.
 - ``g.nodes.csv.gz``: sorted list of unique node identifiers appearing in the
   corresponding ``g.edges.csv.gz`` file. The format is a gzip-compressed csv
   file with one persistent identifier per line.
 
 .. code:: bash
 
     $ docker run                                        \
         --volume /path/to/graph/:/graph                 \
         --volume /path/to/output/:/graph/compressed     \
         --name swh-graph --tty --interactive            \
         swh-graph:latest bash
 
 Where ``/path/to/graph`` is a directory containing the ``g.edges.csv.gz`` and
 ``g.nodes.csv.gz`` files.
 
 Graph compression
 ~~~~~~~~~~~~~~~~~
 
 To start graph compression:
 
 .. code:: bash
 
     $ ./scripts/compress_graph.sh           \
         --input /graph/g                    \
         --output /graph/compressed          \
         --lib /swh/graph-lib                \
         --tmp /graph/compressed/tmp         \
         --stdout /graph/compressed/stdout   \
         --stderr /graph/compressed/stderr
 
 Warning: very large graphs may need a bigger batch size parameter for WebGraph
 internals (you can specify a value when running the compression script using:
 ``--batch-size 1000000000``).
 
 Node ids mapping
 ~~~~~~~~~~~~~~~~
 
 To dump the mapping files:
 
 .. code:: bash
 
     $ java -cp /swh/app/swh-graph.jar       \
         org.softwareheritage.graph.backend.Setup /graph/compressed/g
 
 This command outputs:
 
-- ``g.nodeToSwhMap.csv``: long node id to string persistent identifier.
-- ``g.swhToNodeMap.csv``: string persistent identifier to long node id.
+- ``g.node2pid.csv``: long node id to string persistent identifier.
+- ``g.pid2node.csv``: string persistent identifier to long node id.
 
 REST API
 ~~~~~~~~
 
 To start the REST API web-service:
 
 .. code:: bash
 
     $ java -cp /swh/app/swh-graph.jar       \
         org.softwareheritage.graph.App /graph/compressed/g
