DDC Code (Value) & Description (Genre)
Quote:
The Library Codes "lc_genre" is merely the "Description" of the DDC "Code" value itself. Likewise, the "lc_lcc_genre" is merely the "Description" of the LCC "Code" value itself. You decide in LC configuration which of the 2 choices to default to using in LC (DDC or LCC), although it is possible to use both, just not in a single click. Examples from the original .csv file used to load LC's DDC values & descriptions: Quote:
I wrote LC for my personal use in 2015, and I still much prefer the "flat" values with the ">". However, as described just above, I allowed for other personal tastes. Please yourself. DaltonST |

I have started getting errors with Library Codes in the past couple of days. Example debug output:
Code:
LC is deriving DDC/LCC from ISBN/ISSN: 1 in api: Searching for: stdnbr=9780060515188 http://classify.oclc.org/classify2/Classify?stdnbr=9780060515188&summary=false Connection Error: syntax error: line 1, column 62 Likely inability to connect to the Internet. Verify network connection and retry. Error: returning from api: NONE NONE NONE number of books in selected_books_list to be re-selected after cache refresh: 1 LC is deriving DDC/LCC from ISBN/ISSN: 1 in api: Searching for: stdnbr=9780316462440 http://classify.oclc.org/classify2/Classify?stdnbr=9780316462440&summary=false Connection Error: syntax error: line 1, column 62 Likely inability to connect to the Internet.

Has your API key expired perhaps? |

What makes you think I have ever had an API key? If they require one, then the plugin is DOA for metadata coming from the Classify API. DaltonST |

Well, because the plugin used to work. A change in the API that the plugin was previously relying on is, of course, another sensible explanation for the breakage.
I get redirected to this URL which points to this page documenting the process to apply for an API key. Although there's no mention of any cost associated with acquiring an API key, the application form does seem to want to know your associated “Institution”. If it's really DOA, that's too bad. The automated FAST tagging was especially very nice. Regardless of its future, thank you very much for the useful plugin. |

I did a little more poking around on the OCLC website and found this page about the Classify API specifically. It says:

Before I started using this plugin, I had a web search set up in Calibre's "Search the Internet" dropdown to query ISBNs via the web demo of Classify:
http://classify.oclc.org/classify2/ClassifyDemo?search-standnum-txt=9781415942673 http://classify.oclc.org/classify2/C...Oliver%20Sacks Classify's web demo still works, so perhaps the codebase can be refactored to use webscraping if the API can't be used without a key anymore? |

It was an extremely useful plugin indeed. It sounds like RIP?

Since someone stated that it was easy to get one for "non-commercial" purposes, and since Calibre is free, Open-Source and the epitome of "non-commercial", I would think every user should be able to get one.
I can add a place in customizing to specify a user's API Key, and then use that in the API. Obviously I cannot test any changes without an actual API Key. If someone would like to share their key with me privately via PM so I could test the plugin code changes, that would be wonderful, since I no longer personally use LC since my 50,000 epub library is fully updated using all of my plugins that I wrote specifically for it. I am spending my time elsewhere now. DaltonST |

I just ran into the same problem. The "request for key" page wants institutional info only. I have sent them an email to see if they will provide a key for our use. Will let you know when they get back. I use this plugin all the time and would be extremely unhappy to see it disabled.

webservices are. Luckily they provide test keys This "production key" is entirely unrelated I suppose. On a serious side - I found a mildly relevant feedback form for questions, asked about keys for individuals, will copy here if they reply. |

Around early March the plugin stopped working for myself too. Sad. It was an incredibly useful tool.

Version 1.0.55 No API: Life-Support Replacement for API
Version 1.0.55 - 2023-03-31 No API: Life-Support Replacement for API that requires a Key since December 2022.
This version only populates: DDC; LCC; FAST Tags. The creation of an LC Genre based on LCC or DDC also works, of course, as long as DDC or LCC are populated. Worldcat.org also requires an API key, since the same folks who own Classify own Worldcat. So, the other metadata obtained from Worldcat is not available. There are zero guarantees as to the lifespan of this life-support version. The same folks who require the API Key might decide to further limit access to old-fashioned webscraping without notice.
