closes#76, implement extensible search/retrieval architecture for obtaining metadata
OpenURL COinS lookup is now implemented using a real search architecture system. at the moment, it works with Open WorldCat for books, CrossRef for journal articles (provided the COinS object contains a DOI or an ISSN), and PubMed when a PMID is available.
OpenURL lookup now works for books. this means that all that's necessary to add scrapable book metadata to a page is an ISBN, as shown below:
<span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.isbn=1579550088"></span>
also, we can now scrape Open WorldCat and Wikipedia Book Sources pages with no specialized code involved.
i'm still looking for a better way of looking up journal article metadata. it's currently implemented with CrossRef, but CrossRef simply will not work without a DOI, and is also incomplete (only holds the last name of the first author).
closes#4, Make printable version
- moves functions for creating and deleting hidden browser objects to scholar.js (from ingester.js), since these are necessary for printing as well
- allows saving bibliography in HTML or printing bibliography. style support is not yet complete (pending finalization of 0.9 version of CSL specification).
closes#100, migrate ingester to Scholar.Translate
closes#88, migrate scrapers away from RDF
closes#9, pull out LC subject heading tags
references #87, add fromArray() and toArray() methods to item objects
API changes:
all translation (import/export/web) now goes through Scholar.Translate
all Scholar-specific functions in scrapers start with "Scholar." rather than the jumbled up piggy bank un-namespaced confusion
scrapers now longer specify items through RDF (the beginning of an item.fromArray()-like function exists in Scholar.Translate.prototype._itemDone())
scrapers can be any combination of import, export, and web (type is the sum of 1/2/4 respectively)
scrapers now contain functions (doImport, doExport, doWeb) rather than loose code
scrapers can call functions in other scrapers or just call the function to translate itself
export accesses items item-by-item, rather than accepting a huge array of items
MARC functions are now in the MARC import translator, and accessed by the web translators
new features:
import now works
rudimentary RDF (unqualified dublin core only), RIS, and MARC import translators are implemented (although they are a little picky with respect to file extensions at the moment)
items appear as they are scraped
MARC import translator pulls out tags, although this seems to slow things down
no icon appears next to a the URL when Scholar hasn't detected metadata, since this seemed somewhat confusing
apologizes for the size of this diff. i figured if i was going to re-write the API, i might as well do it all at once and get everything working right.
- fixes a bug that could result in the Scrape Progress chrome thingy sticking around forever
- makes chrome thingy disappear when URL changes or when tabs are switched
- changes scrapers table to translators table; all import/export/web translators now belong in this table
- adds Scholar.Translate to handle translation issues. eventually, Scholar.Ingester.Document will become part of this interface
- adds Scholar_File_Interface (in fileInterface.js) to handle UI for export and eventually import. (David, when you have time, please connect Scholar_File_Interface.exportFile to a button.)
- adds an export translator for MODS. all of our metadata, but not our hierarchy (projects, etc.) translates directly and unambiguously into valid MODS. eventually, we can use RDF or another format to handle hierarchy.
- adds utilities.getVersion() and utilities.inArray() for simplified scraper coding
- fixes minor interface issues with the nifty chrome scraping status window
- Move processDocuments, a function for loading a DOM representation of a document or set of documents, to Scholar.Utilities.HTTP
- Add Scholar.Ingester.ingestURL, a simplified function to scrape a URL (closes#33)
