Maritime Digital Trade Glossary

Plain-language definitions of the legal and technical terms behind electronic bills of lading, qualified electronic signatures, and MLETR — with the Turkish equivalents. Written by a Master Mariner, not copied from a dictionary.

Electronic Bill of Lading (eBL) / Elektronik Konşimento — A bill of lading issued and transferred electronically. A bill of lading is a receipt for cargo, evidence of the carriage contract and, critically, a document of title. Making it electronic is easy; making the electronic version legally count as a document of title is the hard part.

Document of Title / Kıymetli Evrak — A document whose holder is legally entitled to the goods it represents; transferring the document transfers the right to the goods. Under Turkish law a bill of lading is kıymetli evrak — and that status is exactly what electronic form does not yet reliably carry.

MLETR / Elektronik Devredilebilir Kayıtlara İlişkin Model Kanun — UNCITRAL’s 2017 template that lets an electronic record be the functional and legal equivalent of a paper transferable document, replacing “possession” with “exclusive control.” A model, not binding law — each state must enact it. Türkiye has not.

Exclusive Control / Münhasır Kontrol — The digital replacement for physical possession. A system provides exclusive control when only one person can use, transfer or dispose of the record at any moment, and can prove it. MLETR Art. 11 — the cryptographic bar an eBL must clear to be paper-equivalent.

Singularity / Tekillik — The property that a transferable record cannot be duplicated into two valid originals — there is one, and only one, original at any time. Without it, a digital document of title is worthless. MLETR Art. 10.

Possession / Zilyetlik — Physical control of a thing. Turkish property law (TTK Art. 1230) requires transfer of possession of a negotiable instrument to transfer the rights attached to it. Electronic data has no “possession” in Turkish law yet — the root of the Sovereign Bottleneck.

Qualified Electronic Signature (QES) / Nitelikli Elektronik İmza (NES) — The highest signature tier: an advanced signature backed by a qualified certificate and created by a qualified device. Under Law No. 5070 Art. 5 it equals a wet-ink signature — except for negotiable instruments and guarantee contracts (Art. 5(2)).

Law No. 5070 Art. 5(2) Exception / 5070 m. 5/2 İstisnası — The provision that excludes kıymetli evrak (negotiable instruments — bills of lading, cheques, promissory notes) and guarantee contracts from valid execution by electronic signature. Why an eBL cannot be endorsed by e-signature under current Turkish law.

Sovereign Bottleneck / Egemenlik Darboğazı — The gap between a platform network’s contractual recognition of an eBL and statutory document-of-title recognition under national law. Technology does not close it; only the legislature can. Maresign’s core thesis.

Paper Fallback / Kâğıda Dökme — What happens in practice when a legally valid eBL reaches a jurisdiction that does not recognise it statutorily: it gets printed for customs or the bank. The visible symptom of the Sovereign Bottleneck.

Contractual vs. Statutory Recognition / Sözleşmesel vs. Yasal Tanınma — Contractual: the eBL binds the parties who signed the platform rulebook. Statutory: the eBL binds the whole world — third parties, customs, courts, banks. Türkiye today has the first, not the second.

MLIT / Kimlik Yönetimi ve Güven Hizmetlerine İlişkin Model Kanun — UNCITRAL instrument for cross-border recognition of electronic identities and signatures. Lets a signature issued in one country be trusted in another — the missing piece for a Middle Corridor eBL transfer.

MLAC / Otomatik Sözleşmelere İlişkin Model Kanun — UNCITRAL instrument giving legal standing to contracts concluded by automated systems (smart contracts). Lets an eBL transfer execute automatically and still be legally valid.

eIDAS / eIDAS Tüzüğü — EU Regulation 910/2014 on electronic identification and trust services. Art. 25(2) gives a qualified electronic signature the same legal effect as a handwritten one across the EU — the reference standard Turkish QES is measured against.

UK ETDA 2023 / Birleşik Krallık Elektronik Ticaret Belgeleri Kanunu — The UK’s MLETR-aligned law, in force 20 September 2023. Gives electronic trade documents the same effect as paper. Matters to Turkish parties because most charterparties and bills of lading are governed by English law.

DCSA / Dijital Konteyner Taşımacılığı Birliği — Digital Container Shipping Association; sets eBL interoperability standards among carriers. Solves platform interoperability — but not national statutory recognition. Interoperability is not legal validity.

Middle Corridor / Orta Koridor — The multimodal (rail/sea/road) trade route from Asia to Europe through the Turkic states. Its only competitive edge is speed — which paper documents at each border destroy. Paperless trade is its existential business case, not a nice-to-have.

OTS DEPA / TDT Dijital Ekonomi Ortaklık Anlaşması — The Organization of Turkic States’ Digital Economy Partnership Agreement (Law No. 7583, ratified by Türkiye 20 June 2026). A cooperation framework — it does not transpose MLETR — but its promise of mutual QES recognition could make an İstanbul signature valid at Aktau.
