Include instructions for reader to publish it to whatever media analog of today's web page.
So basically stay away from technology, get information encoded into lowest and most resilient physical material and rely on future generation to publish and/or update it's content.
Unfortunately, I can’t find it again at the moment.

Sure, QR codes are unlikely to be useful in 500 years, but if they have the above properties, they are just as good as anything else. If civilization endures, I am sure they'll be decodable in 5 centuries (whether they are preserved is altogether another matter).
The Rosetta Disk is the physical companion of the Rosetta Digital Language Archive, and a prototype of one facet of The Long Now Foundation's 10,000-Year Library. The Rosetta Disk is intended to be a durable archive of human languages, as well as an aesthetic object that suggests a journey of the imagination across culture and history. We have attempted to create a unique physical artifact which evokes the great diversity of human experience as well as the incredible variety of symbolic systems we have constructed to understand and communicate that experience.
The Disk surface shown here, meant to be a guide to the contents, is etched with a central image of the earth and a message written in eight major world languages: “Languages of the World: This is an archive of over 1,500 human languages assembled in the year 02008 C.E. Magnify 1,000 times to find over 13,000 pages of language documentation.” The text begins at eye-readable scale and spirals down to nano-scale. This tapered ring of languages is intended to maximize the number of people that will be able to read something immediately upon picking up the Disk, as well as implying the directions for using it—‘get a magnifier and there is more.’
On the reverse side of the disk from the globe graphic are over 13,000 microetched pages of language documentation. Since each page is a physical rather than digital image, there is no platform or format dependency. Reading the Disk requires only optical magnification. Each page is .019 inches, or half a millimeter, across. This is about equal in width to 5 human hairs, and can be read with a 650X microscope (individual pages are clearly visible with 100X magnification).
