A Java implementation of data structures and code to read/write Brat standoff format. https://github.com/yfpeng/pengyifan-brat
(from brat standoff format)
Annotations created in brat are stored on disk in a standoff format: annotations are stored separately from the annotated document text, which is never modified by the tool.
For each text document in the system, there is a corresponding annotation file. The two are associated by the file naming convention that their base name (file name without suffix) is the same: for example, the file
DOC-1000.ann contains annotations for the file
Within the document, individual annotations are connected to specific spans of text through character offsets. For example, in a document beginning “Japan was today struck by …” the text “Japan” is identified by the offset range 0..5. (All offsets all indexed from 0 and include the character at the start offset but exclude the character at the end offset.)
