Overview ¶
Package marcview is the MARC half of the dual-view editor (tasks/049): it materializes a grain's records as an editable field array (via the framework-aware decode, so overrides shadow and verbatim sidecar fields appear), and writes an edited array back as a *diff* -- the edited record re-crosswalks to BIBFRAME, the result is compared to the original decode per (subject, predicate) group, and only the changed groups land as editorial quads with the tasks/042 override semantics. Untouched fields are byte-for-byte no-ops; crosswalk-lossy tags round-trip through the lcat:marcVerbatim sidecar instead of the graph.

Variables ¶
var ErrValidation = errors.New("marcview: invalid record")
ErrValidation reports an edited record that cannot be saved.
Functions ¶
func DocToRecord ¶
DocToRecord rebuilds the full MARC record from a field array (every field included, lossy or not) -- the inverse of RecordToDoc.
Types ¶
type Field ¶
type Field struct {
Tag string `json:"tag"`
Ind1 string `json:"ind1,omitempty"`
Ind2 string `json:"ind2,omitempty"`
// Value carries a control field's raw data (tag < 010).
Value string `json:"value,omitempty"`
Subfields []Subfield `json:"subfields,omitempty"`
// Lossy carries the fidelity table's reason when the tag does not
// survive the crosswalk -- the editor's non-blocking warning. Edits to
// lossy tags persist via the lcat:marcVerbatim sidecar.
Lossy string `json:"lossy,omitempty"`
}
Field is one MARC field row of the editing grid.
type RecordDoc ¶
type RecordDoc struct {
// Node is the grain node the record maps to (its Instance IRI, or the
// Work IRI for an instance-less record).
Node string `json:"node"`
Leader string `json:"leader"`
Fields []Field `json:"fields"`
}
RecordDoc is one materialized MARC record.
func RecordToDoc ¶
RecordToDoc materializes one parsed MARC record as a field array -- the copy-cataloging search results and staged imports speak this shape too (tasks/050).
