Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating stable location identifiers. One of the methods includes generating, for each relevant location in an existing file, a signature for the relevant location using at most a predetermined quantity of characters surrounding the relevant location; obtaining, for a first file that includes location information for the existing file, data that identify one or more locatable strings in the existing file and, for each locatable string, a corresponding location within the existing file; determining, for each particular location associated with a locatable string from the one or more locatable strings in the existing file, a respective corresponding signature; and generating the first file that includes, for each locatable string from the one or more locatable strings, the respective corresponding signature that uniquely identifies the relevant location on which the locatable string occurs in the existing file.
