Solr Scalable Icon

* DollarDays is hosting a pair of scalable SVG files (Zip Archive) for use by other Solr implementers. Simply export the SVG (using Inkscape for example) to a bitmap graphic (PNG, GIF, JPG) of whatever size you desire for placement on your Solr powered website.

Notes

It would be good to add some scale information here, where possible: how many documents do these sites index, how many search requests per day, what kind of servers, etc. If someone could determine what kind of license, copyright, etc the current Solr logo has, it could be included as a text file in the zipped SVG file and could make for a clearer permission statement.
