Asset disposal (v1)
Asset disposal is one of Demiton's published registers for Australian civil construction. Plant and equipment written off, sold or scrapped. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
