{"body": {"type": "/type/text", "value": "### futurelib\r\n\r\nOpen Library provides an exciting opportunity for the librarianship community. For the first time, we'll have an open, public, curated, universal catalog of all books. But this also presents an enormous challenge: we need to develop a schema for all that book information.\r\n\r\nLike the MARC format, we'll want our schema to contain all the important bibliographic information that librarians want to collect about books. But we'll also want to take advantage of all the things we've learned since MARC. We'll also want to store some information that's of less importance to librarians, but of more importance to publishers (like the ONIX format stores) and arbitrary users. And we'll have to figure out how to present all this data in a way that makes sense to relatively untutored users.\r\n\r\nWe're currently calling this new schema _futurelib_ and we hope to hold a series of meetings for geeks, librarians, and booklovers to come together and hash out a proposal. To aid in this discussion, we have a page of [library terminology](lib_defs) with definitions. Feel free to add new terms or definitions to the list.\r\n\r\nIn the meantime, you might be interested in [our current draft schema](schema) which we threw together to get the demo up. There is also a [crosswalk](infogami-dc) from the Infogami data elements to Dublin Core.\r\n\r\n### OLNs\r\n\r\nBut it's not just schemas. A universal catalog will also allow us to have a new, universal book identification scheme -- something akin to ISBNs or ISTNs, but for _all_ books, not just recent ones. We're currently calling this scheme _OLN_ for Open Library Number, but we'll need your help hashing out how it should work.\r\n\r\n### Some useful data\r\n\r\n* [MARC language codes with translation](http://www.archive.org/details/MarcLanguageCodesWithFullDisplay)\r\n* [LC Class numbers outline](http://www.archive.org/details/LcClassificationA-z). This file combines all of the documents from http://www.loc.gov/catdir/cpso/lcco/, and is in text format with tabs for the levels.\r\n* [First two levels of LC Class numbers](http://www.archive.org/details/LcClassificationLevels1-2). This file has the LC Classification at the level of one character and two character codes, followed by a display form (eg. H\tSocial sciences (General), HA\tStatistics). The codes and display forms are separated by a tab character.\r\n\r\n### Merging\r\n\r\nA big part of our problem is collecting book information from multiple sources and merging it together: merging records from publishers and from libraries, merging together the same book when in different libraries, merging together the same book that has different editions, etc. We'll need your help developing algorithms that can do this effectively as well as in correcting the results when the algorithms go wrong. \r\n\r\nWe're starting with a version of the [merge algorithm](http://www.kcoyle.net/merge.html) developed for the [MELVYL](http://melvyl.cdlib.org) catalog.\r\n\r\nThere is also a page where we can lay out different options for creating [Work sets](http://openlibrary.org/about/frbrization) --  (also known as FRBR-ization).\r\n\r\n### Data collection\r\n\r\nWe want as much data as we can get our hands on. If you know anyone with data or know how to get some, please get in touch.\r\n\r\nIf you are creating a data dump for us, it's best if you can use a standard format (MARC21, MARCXML, UNIMARC, etc.). Be sure to include in each record fields that give:\r\n\r\n* your local record ID (MARC 001)\r\n* something that identifies the source of the record (your system or institution) (MARC 003)\r\n* the version date (either the last date the record was updated, or the date of the data dump) (MARC 005)\r\n\r\n### Further info\r\n\r\nWe're going to keep working on and discussing all these issues.
