OpenGrape is a Java-based Open Graph parser

The Open Graph Protocol is a metadata standard that enables services, like social media applications, to fetch previews of webpages, such as thumbnail images and summaries.

This Orbit Earth OpenGrape is a friendly fork of the excellent Kientux OpenGrape, which is a Java port of the Swift OpenGraph.

Installation

Unlike Kientux OpenGrape, this version is not hosted in a public Maven repository, but must be built and installed locally using mvn install.

<dependency>
    <groupId>social.orbitearth</groupId>

Usage

Map<OpenGrapeMetadata, String> metadata = og.fetch("https://opengraphprotocol.org/");
