IriUtils

Returns the canonical form of iri for equivalence comparison: lower-cases the scheme and host, removes ./.. dot-segments, and normalizes percent-encoding via URI. Path case, the trailing slash, and any fragment are preserved — a file x and a container x/, or two different #fragments, are genuinely distinct resources/agents and must NOT be unified. Falls back to the raw string if iri doesn't parse.

Escapes iri for safe emission inside <...> angle brackets in N-Triples / Turtle / N3. The IRIREF production forbids control characters (U+0000–U+0020) and < > " { } | ^ \` unescaped; we replace each with a \\uXXXX UCHAR so a hostile or merely unusual IRI can't break out of the term and corrupt the serialized document. Returns the input unchanged when it contains none of those characters.

Returns true if iri identifies an LDP container (URI ends with /). Per the Solid Protocol, the / character indicates a hierarchical container relationship.

Returns true if iri is a syntactically valid absolute IRI with an http or https scheme (the only schemes used in Solid).

Returns the parent container IRI of iri, or null if iri is the storage root (no parent).

Resolves reference against base, returning the resolved IRI string. Handles relative references such as /path/to/resource.

Returns the last path segment of iri (the resource name), excluding any trailing slash.

Returns true if a and b denote the same IRI once canonical-ized.

Strips the trailing slash from iri if present.

Appends a trailing slash to iri if absent, returning a container IRI.

Attempts to parse iri as a URI, returning null on failure instead of throwing.
