00 — Overview

R10 reference application. Built from the v0.14 Work & Supply reference pack. The demo data is fictional; manufacturer names and part numbers are illustrative.

What Catalogue is

Catalogue answers "what is this item?" — nothing about how many there are (that is Inventory) or what they cost and who supplies them (Purchasing, Supplier). Keeping the definition in one place means every application describes a part the same way, and a change — an item superseded, a substitute approved — is made once.

The 7 models

Items (3) - CatalogueItem — the item: code, description, type (part, consumable, rotable, repairable, tool, material, bulk material, service), unit, tracking flags (serial, lot, shelf life), manufacturer and part number, status, and what supersedes it. - CatalogueIdentifier — other numbers the item is known by: manufacturer, OEM, legacy (e.g. an old SAP material number), barcode. - CatalogueStatusHistory — every status change with its reason.

Substitutes & Fitment (2) - ItemSubstitution — item A may be replaced by item B: direct, conditional (with conditions and approval), superseded-by, temporary. - ItemApplicability — where an item may (or may not) be fitted: asset type / model / position, approved, preferred, conditional or prohibited.

Categories & Organisations (2) - CatalogueCategory — a hierarchy of categories. - Organisation — manufacturers (and suppliers named on items).

The demo items

The first three keep the network ids Work Management and Inventory already use, so the item codes in those applications link here.
