.OPML

📌 One more apparent variation of the .OPML data file sample correlates with an outline document composed, written, and opened up in OPML (Outline Processor Markup Language) clauses. Essentially, the noted principle serves for exchanging lists of Web-aggregated feeds (such as .RSS feeds, for instance) between trusted Web-feed aggregators. Besides, the noted file methodology is irreplaceable for other common outlining aims and targets. Each of the suggested .OPML-wrapped file extension formations embraces the following sections or XML elements:

• OPML version - e.g. “2.0”
• Head - includes open metadata that explicitly describes the requested content
• Body - covers the content of the suggested outline
• Outline - encompasses a line in the outline.

How to open an .OPML file?

📌 The specified outline file arrangements are available for research, tracking, monitoring, and opening due to interference with ConceptDraw MINDMAP, Tkoutline, OmniOutliner, or Corel MindManager toolkits. As a suitable alternate option, you can tweak the OPML Viewer web-service, runnable from any assigned web-browser available within your operating ecosystem.
