@boarteam/fix-dict-fix50sp2

The complete FIX 5.0 SP2 dictionary as data (1,452 fields / 115 messages / 28 datatypes), self-contained over the FIXT.1.1 transport, for the @boarteam/fix engine. The FIXT session envelope (header/trailer, ApplVerID(1128), DefaultApplVerID(1137)) plus the 7 session messages and the 108 base-SP2 application messages in one dictionary — a drop-in for the same single-dictionary API the 4.2/4.4 dicts use. Generated from the QuickFIX/J FIX50SP2.xml + FIXT11.xml data dictionaries and cross-checked against quickfix-go's independently-maintained FIX50SP2.xml by a CI drift gate — never hand-maintained.

FIX 5.0 messages travel over FIXT.1.1: tag 8 carries FIXT.1.1, and the application version rides on DefaultApplVerID(1137) (required on Logon; 9 = FIX 5.0 SP2) with the optional per-message header override ApplVerID(1128). This dictionary models exactly that: dictionary.version === 'FIX.5.0SP2', dictionary.beginString === 'FIXT.1.1', dictionary.applVerID === '9'.

import { createFixEngine } from '@boarteam/fix';
import { dictionary, message, Enums } from '@boarteam/fix-dict-fix50sp2';

const fix = createFixEngine(dictionary);
// A FIXT Logon, typed: DefaultApplVerID is required by the LogonBody type.
const wire = message('A')
  .set('EncryptMethod', '0')
  .set('HeartBtInt', 30)
  .set('DefaultApplVerID', Enums.ApplVerID.FIX50SP2) // '9'
  .render({
    SenderCompID: 'ME',
    TargetCompID: 'YOU',
    MsgSeqNum: 1,
    SendingTime: '20260801-12:00:00',
  });
// wire starts "8=FIXT.1.1|9=..."

Exports: dictionary (the data), Tags/TagNames, MsgType/MsgTypeNames, Enums (e.g. Enums.ApplVerID.FIX50SP2 === '9'), a top-level const + same-name type per enumerated field, DICTIONARY_VERSION ('FIX.5.0SP2' — the application version; tag 8 carries dictionary.beginString, 'FIXT.1.1'), and the typed message API: message, MessageBodies (admin + application bodies), isMessageType, MessageOf<M>.

Provenance & coverage

• Structure: QuickFIX/J FIX50SP2.xml (base SP2: 108 messages — deliberately not the quickfix C++ copy, which was regenerated at EP280 and is effectively FIX Latest) + FIXT11.xml (envelope + 7 session messages), merged at build time.
• Descriptions: FIX Orchestra OrchestraFIXLatest.xml (EP307) for the application layer + FIXTSession.xml (EP247) for the session layer, both Apache-2.0. Coverage: 99.9% of fields, 99.7% of enum values; the remainder is recorded in dictionary.coverageGaps.
• Cross-check: compared structurally against quickfix-go's FIX50SP2.xml (a later EP level: 110 messages / 198 components); the reviewed EP-drift differences are pinned in a committed baseline and CI fails on any new drift.
• Known limitations: XMLnonFIX(n) is not shipped (QuickFIX/J master comments it out and quickfix-go omits it; restoring it later is additive). No conditional-required (C) markings — the only historical source of C facts is license-restricted, so like the 4.2 dict all members are Y/N (see the project README's coverage notes).

Requires @boarteam/fix as a peer dependency.
