Hikayesi

OPML NASIL
ORTAYA ÇIKTI.

OPML — Outline Processor Markup Language — was created by Dave Winer at UserLand Software in 2000 as an XML format for storing hierarchical outlines. Winer was one of the early blogging pioneers, and OPML became the de-facto format for sharing lists of RSS feed subscriptions between feed readers. Every RSS client (NetNewsWire, Google Reader, Feedly, Inoreader) imports and exports OPML files; this is the standard way to migrate your RSS subscriptions from one reader to another.

OPML’s use broadened beyond RSS into outline editors, mind-mapping tools (Scrivener, OmniOutliner), and lesson-planning software. The format is intentionally simple — nested `<outline>` elements with arbitrary attributes — which makes it both easy to implement and endlessly extensible. OPML’s continued existence, 25 years after Google Reader’s death, is proof that standards designed for portability outlive the tools that created them.

MERAK EDİLENLER VE
İLGİNÇ BİLGİLER.

Every RSS reader — NetNewsWire, Feedly, Inoreader, Miniflux — imports and exports OPML as the standard subscription-list format.

Google Reader's 2013 shutdown sent millions of users scrambling to export their subscriptions as OPML before the deadline.

Dave Winer also co-authored the RSS 0.92 and 2.0 specs — the same blogging pioneer who shaped the RSS ecosystem created its migration format.

OmniOutliner, Scrivener, and Workflowy all support OPML import — outlines are portable across the writing-app landscape.

OPML is XML with exactly one required element: nested `<outline text="..."/>`. That simplicity is why it's lasted 25 years.

GÜÇLÜ YÖNLER VE
SINIRLAMALAR.

Güçlü Yönler

Standard RSS subscription interchange format.
Simple XML — easy to parse and generate.
Highly extensible via arbitrary attributes.
Supported by every major outline and RSS tool.

Sınırlamalar

XML verbosity — larger than a JSON-based equivalent.
Specification is loose — different tools disagree on edge cases.
Primary use (RSS reading) has shrunk dramatically since Google Reader.
No strong central stewardship.
