OpenVINO ships models as two sibling files:
model.xml topology + per-tensor (offset, size, dtype, shape)
model.bin raw weight blob; each Const layer's data
lives at the offset+size declared in the XML.
This is the cleanest tensor-archive format of all the
ones the substrate has ingested so far — "raw bytes at
offset+size in a sibling file."
SCOPE — what wave 39 does
Parse `.xml` streaming via quick-xml (already a
workspace dep). Extract every `<layer type="Const">`'s
`name` + `<data element_type=, shape=, offset=, size=/>`
attributes. mmap the sibling `.bin`. Surface as:
OvModel {
xml_path, bin_path,
net_name, ir_version,
tensors: Vec<OvTensorInfo>,
bin_mmap,
}
OvTensorInfo { id, name, dtype, shape, bin_offset, bin_size }
read_openvino_ir(path/to/model.xml) auto-resolves the
sibling .bin (same basename + .bin extension). On load
every Const layer's (offset, size) is bounds-checked
against the .bin file length, so corrupt XML refusing
to fit triggers OvError::BinOutOfBounds at parse time
rather than at first slice.
tensor_bytes(&t) returns Some(&[u8]) into the .bin
mmap. The substrate primitive.
DTYPE COVERAGE
All documented OpenVINO IR element types:
f64 f32 f16 bf16
i64 i32 i16 i8 i4
u64 u32 u16 u8 u4 u1
boolean string
f8e4m3 f8e5m2 f8e8m0 f4e2m1
nf4
Case-insensitive parse. Unknown values pass through as
Unknown(String) — same forward-compat strategy as the
other readers.
SCOPE — what wave 39 does NOT do
No operator graph execution. No edge / port traversal.
No reshape / fuse pattern matching. JouleClaw has its
own kernel suite.
