Without having first extracted it from the database, I can’t give any, because the extraction from the database is covered by the rights on the database. It is theoretically possible that your extraction is not substantial: You could have a way of taking the data for an “item” and inserting its data into a blog. It may be contained in your blog’s database, you might add a couple of extra attributes for your blog, but still not be required to distribute any part of your blog’s database, including the modified item. If we assumed there were rights in this extraction (e.g. sweat of the brow, involving some decision about how to map it, or artistic), then the licence on the content comes into play and you should also abide by those terms. If the licence were stronger than DbCL, for example including attribution and/or share alike, you may be required to list the contributors and/or also provide access to a suitable “source” form (e.g. OSM format) of the data.
