The previous commit's fix to 03_Document_Parsing.ipynb collapsed the
cell's source array into a single string and dropped the trailing
newline. Restore the original array-of-lines formatting so the diff
is limited to the corrected badge URL.
Seven introduction notebooks linked to a different notebook's filename
in their Colab badge (off-by-one numbering), sending readers to the
wrong notebook or a 404. Point each badge back at its own file.
Add a Cite Us section to the README with BibTeX citation info, and
align it with docs/citation.md (author/organization: Semantica, 2026).

_turtle_object() wrote an IRI-valued metadata value (currently only
sem:sourceUri, from the "uri" metadata key) straight into `<{value}>`
with no escaping. Turtle/N-Triples IRIREFs exclude control
characters, space, and <>"{}|^`\ unescaped, so a value shaped like
`<goodIRI> . <injected> <p> <o>` closed the reference early and let
the rest of the string be parsed as an attacker-chosen extra triple:
metadata={"uri": "https://x> . <https://injected> <https://p> <https://o"}
produced a well-formed Turtle/N-Triples document containing a triple
the caller never asked for.
RDF/XML was already safe (_rdfxml_metadata_lines runs the value
through _escape_xml before putting it in an rdf:resource attribute),
and JSON-LD is safe by construction (json.dumps makes structural
injection impossible) — only the Turtle/N-Triples "iri" literal path
in _turtle_object was unguarded.
Adds _safe_iri_ref(), a narrow percent-encoder for exactly the
characters an IRIREF may not contain unescaped. It's deliberately not
_as_turtle_iri: that also resolves registered prefixes, which a
metadata value never needs, so a dedicated guard stays simpler than
threading namespaces into a module-level helper that has no `self`.
Two regression tests, parametrised over turtle/ntriples: the `>`
delimiter-breaking payload from the report, and a control-character
(newline/tab) variant covering the other half of the excluded set.
Resolves the conflict in semantica/export/rdf_exporter.py between this
branch's metadata clauses (entity/graph metadata statements) and
main's IRI-normalization and XML-escaping hardening
(_as_turtle_iri / xml_escape, landed after this branch's last sync).
Kept both: entity/relationship/graph subjects and objects now go
through _as_turtle_iri (Turtle) or _as_turtle_iri + xml_escape
(RDF/XML), same as every other identifier in these serializers,
while the metadata-clause list building and graph_uri handling from
this branch are preserved unchanged. graph_uri is now normalized the
same way for consistency with the rest of the file.
Verified: tests/export + tests/ontology (411 tests) and the existing
Turtle-IRI regression suite (test_rdf_exporter_turtle_iris.py, 9
tests) all pass against the merged code.
Matches the README's existing convention for query params inside
HTML attribute URLs (e.g. the Trendshift badge), per review feedback
from Zohaib Hassan and Qodo on this PR.

ProgressTracker attached ConsoleProgressDisplay unconditionally, so any
script or CI job that piped or redirected stdout had one progress bar per
stage written into its output, escape sequences included. A plain
`python demo.py > out.txt` captured 173 bytes of progress-bar noise around
10 bytes of the program's own output.
Console progress is now attached only when stdout is an interactive
terminal, when running under Jupyter, or when SEMANTICA_FORCE_PROGRESS is
set. FileProgressDisplay is untouched, so progress logging still works in
pipelines, and SEMANTICA_DISABLE_PROGRESS keeps its existing meaning and
still takes precedence.
Both progress environment variables are now documented in the README and
the utils reference; SEMANTICA_DISABLE_PROGRESS previously existed only in
the reference page.
Deviations from the issue: the issue suggested disabling the tracker on
non-TTY stdout. This gates the display instead, because disabling the
tracker would short-circuit before FileProgressDisplay and take file
progress logging down with it, and the ~20 modules that set
`progress_tracker.enabled = True` in __init__ would need the property
setter taught about TTY state to avoid undoing it. Gating the display
leaves both alone.
Design note: the claim comment on the issue proposed an
`enabled: Optional[bool] = None` constructor opt-in; during implementation
the opt-in became SEMANTICA_FORCE_PROGRESS, which needs no signature change
and follows the NO_COLOR/FORCE_COLOR convention. Known limitation: TTY
detection runs once at tracker construction (the tracker is a process-wide
singleton), so a process that redirects stdout after first use needs the
env vars to change behaviour.
Fixes#1185
_as_turtle_iri() re-encoded absolute IRIs wholesale, turning already-valid
percent-escapes like %20 into %2520. Only spans outside existing valid
%XX escapes are quoted now, so malformed escapes (%zz) still get repaired
while valid ones pass through unchanged.
serialize_to_ntriples()/serialize_to_rdfxml() also passed only the
@context-derived namespaces into _as_turtle_iri(), which shadowed the
built-in semantica:/rdf:/rdfs:/owl: prefixes entirely whenever any
@context was present. _as_turtle_iri() now always merges the built-ins
with whatever namespaces the caller passes.
The adapter inventory and connection examples referenced classes that
don't exist in semantica.graph_store (Neo4jGraphStore, NeptuneGraphStore,
AgeGraphStore) and used constructor kwargs that don't match the actual
adapters (username vs user, host vs endpoint, url vs endpoint, etc.),
verified against each adapter's real __init__ signature and by
constructing every example against the live classes.
- Correct class names: Neo4jStore, AmazonNeptuneStore, ApacheAgeStore
- Fix kwargs for all seven examples to match actual constructors
- Fix ApacheAgeStore's connection_string to libpq keyword=value format
instead of a postgresql:// DSN, which the adapter doesn't accept
- Reclassify Anzo from interface/BYO to built-in — AnzoStore is a real,
exported, tested adapter
- Add the two adapters missing from the inventory: FalkorDBStore and
OxigraphStore
- Replace the literal password='password' example with an env var
- Note a real RDF4JStore bug found while verifying the RDF4J example:
repository_id is a named constructor parameter but the implementation
reads it from **config instead, so it's silently ignored and the
store always connects to the "default" repository
vector_store_config.get_all() always includes a "dimension" key, so
forwarding it via **config into VectorIndexer(dimension=dimension, **config)
raised "got multiple values for keyword argument 'dimension'" any time the
default index-creation path ran with the default config — including
`semantica embed index`, which is exactly the second half of the #994
quick-start pipeline this PR fixes.
