BerkeleyLibrary::TIND

Utility gem for working with the TIND DA digital archive.

Installation

In your Gemfile:

gem 'berkeley_library-tind'

In your code:

require 'berkeley_library/tind'

Configuration

To access the TIND API, you will need to set:

the base URL for your TIND installation (e.g. https://digicoll.lib.berkeley.edu/)
the TIND API key (see the "API Token Generator" article on docs.tind.io. TIND's code and docs are inconsistent in their use of "token" and "key". The UI calls it a "key", so that's the term we use here.)

These can be set directly, via accessors in the BerkeleyLibrary::TIND::Config module; if they are not set, a value will be read from the environment, and if no value is present in the environment and Rails is loaded, from the Rails application configuration (Rails.application.config).

Value	Config	ENV	Rails
TIND base URI	`:base_uri`	`LIT_TIND_BASE_URL`	`:tind_base_uri`
API key	`:api_key`	`LIT_TIND_API_KEY`	`:tind_api_key`

Note: The TIND base URI can be set either as a string or as a URI object, but will always be returned as a URI object, and an invalid string setting will raise URI::InvalidURIError.

Alma configuration

When mapping Alma records to TIND (see below), this gem uses berkeley_library-alma to load Alma records. The scripts in the bin directory use the default Alma configuration; see the berkeley_library-alma README for details.

Command-line tool: `tind-export`

The tind-export command allows you to list TIND collections, or to export a TIND collection from the command line. (If the gem is installed, tind-export should be in your $PATH. If you've cloned the gem source, you can invoke it with bin/tind-export from the project root directory.)

Examples:

list collections
```
tind-export --list-collections
```
export a collection as an OpenOffice/LibreOffice spreadsheet
```
tind-export -o lincoln-papers.ods 'Abraham Lincoln Papers'
```
export a collection as an OpenOffice/LibreOffice spreadsheet in exploded XML format, where lincoln-papers is a directory
```
tind-export -f ODS -o lincoln-papers 'Abraham Lincoln Papers'
```
(Note that OpenOffice itself and many other tools get confused by the extra text nodes in the pretty-printed files and won't read them properly; this feature is mostly for debugging.)
export a collection as CSV, to standard output
```
tind-export -f CSV 'Abraham Lincoln Papers'
```

For the full list of options, type tind-export --help. Note that you can set the TIND base URL and API key either via the environment, as above, or as options passed to the tind-export command. If both an explicit option and an environment variable are set for either, the explicit option takes precedence.

Mapping MARC records from Alma to TIND

Transforming Class:

BerkeleyLibrary::TIND::Mapping::AlmaSingleTIND (Transforming one Alma record => One TIND record)
BerkeleyLibrary::TIND::Mapping::AlmaMultipleTIND (Transforming one Alma record => Multiple TIND records)

Source of TIND fields

Mapped from an Alma record (automatically)
Derived from collection information, mms_id, and date (automatically)
- 336$a
- 852$c
- 980$a
- 982$a,$b
- 991$a - (optional)
- 902$d
- 901$m
- 85641$u,$y
Added at the time of transforming TIND record (fields of a collection or its record)
- FFT
- 035$a
- 998$a
- ...

Example

Setup collection information
- 336: type of resource
- 852: collection's repository name
- 980: collection's 980 value
- 982: collection's short name and long name
- 991: collection' restricted name (optional)

def setup_collection
  BerkeleyLibrary::TIND::Mapping::AlmaBase.collection_parameter_hash = {
    '336' => ['Image'],
    '852' => ['East Asian Library'],
    '980' => ['pre_1912'],
    '982' => ['Pre 1912 Chinese Materials - short name', 'Pre 1912 Chinese Materials - long name'],
    '991' => []
  }
  
  # BerkeleyLibrary::TIND::Mapping::AlmaBase.is_035_from_mms_id = true  

  # Flag on getting Alma record using Barcode
  BerkeleyLibrary::TIND::Mapping::AlmaBase.is_barcode = true           
end

Praparing additional fields

Adding field using:
- field methods from module: BerkeleyLibrary::TIND::Mapping::TindField
- Or the original method from Ruby Marc when field method found in above module
  ::MARC::DataField.new(tag, indicator1, indicator, [code1, value1], [code2, value2] ...)

def additional_tind_fields_1
  txt = 'v001_0064'
  url = 'https://digitalassets.lib.berkeley.edu/pre1912ChineseMaterials/ucb/ready/991032333019706532/991032333019706532_v001_0064.jpg'
  fft = BerkeleyLibrary::TIND::Mapping::TindField.f_fft(url, txt)

  f = ::MARC::DataField.new('998', ' ', ' ', ['a', 'fake-value'])
  [fft] << f
end

def additional_tind_fields_2
  txt = 'v001_0065'
  url = 'https://digitalassets.lib.berkeley.edu/pre1912ChineseMaterials/ucb/ready/991032333019706532/991032333019706532_v001_0065.jpg'
  fft = BerkeleyLibrary::TIND::Mapping::TindField.f_fft(url, txt)
  [fft]
end

Transforming one Alma record => One TIND record

setup_collection

# id can be  1)mms_id;  2)Millennium no ; or 3)Barcode
id = 'C084093187'

alma_tind = BerkeleyLibrary::TIND::Mapping::AlmaSingleTIND.new
tind_record = alma_tind.record(id, additional_tind_fields_1)

Or transforming one Alma record => Multiple TIND records

setup_collection

# id can be 1) mms_id; 2) Millennium bib number; or 3) Item barcode
# id = '991085821143406532'
id = 'C084093187'

alma_tind = BerkeleyLibrary::TIND::Mapping::AlmaMultipleTIND.new(id)
tind_record_1 = alma_tind.record(additional_tind_fields_1)
tind_record_2 = alma_tind.record(additional_tind_fields_2)
