  3. Agenda Part 2 10:30 to 11:30 • Customizing and integrating your CONTENTdm site • Web templates • Custom Queries and Results • Configuration files

  4. Agenda Part 3 11:30 to Noon • Handling Finding Aids • Importing EAD files into CONTENTdm

  5. Setting the context: fully engaged in digital library transformation • Library services and collections expanding to encompass all • Traditional to digital • Licensed • Reformatted • Sharing • Preserving

  6. Leveraging resources • Staff time and skills throughout the organization and/or consortium • Existing metadata in some form • Existing digital collections (images and transcripts)

  7. Why? For better customer service • In order to mainstream your processing and amplify your efforts. • Your digital collections should ultimately be mainstreamed into regular workflows, similar to the ones used for other materials (whether that’s done centrally or in a distributed fashion). • This includes selection, technical processing (cataloging, organizing, importing), integration with site vis-à-vis presentation and archiving.

  8. Mainstreaming processing of digital formats(Part 1 of 3) • Importing from other systems to CONTENTdm • Exporting from CONTENTdm • Example of collaborative development for interoperability • CONTENTdm Standard Export • METS transform for import

  9. I. Importing from other systems to CONTENTdm • Metadata only • When records describe items that are not yet scanned • Replace “null” files at later time • Metadata AND their digital files

  10. From an OPAC or other database system When you have… • Individual image files cataloged already • And can export from an OPAC or other dbms Or where you havecompound digital objects ready for migration

  11. Migration steps: • Prepare the collection and the import files • Cross-walk metadata to Dublin Core • Configure the CONTENTdm collection fields • Export and prep data in a tab-delimited ASCII file • Import the file to CONTENTdm

  12. Data prep: Common problems in tab delimited data files • Extra data in columns or rows • Extra tabs at end of line • Extra CRs at end of file (Should only be 1 CR) • Carriage return in metadata, tab in metadata • Files must exist • 0 versus O • Error may occur in previous record, check few rows before and after error • File names are required, not full pathnames

  13. Data prep: Troubleshooting with Excel • Use Microsoft Excel to open the file and view data • Each row should be an item with last column as filename • Work with small batches to find errors – keep adding items until record with error is found • Use Excel’s “CLEAN” function to remove invisible characters • Import images from directory without using tab delimited file • Checks for any type of imaging errors

  14. Demo: MARC to DC • Export MARC records to tab-delimited text file (using ILS or MarcEdit) • Format and clean up the text file to conform to your CONTENTdm Collection schema • Import the file (with or without images) to the Collection

  15. Importing compound objects • For documents, postcards, monographs and picture cubes • Can do singly or in batch • Much easier to start with singles, then set up for batch when process is smooth

  16. Migrate compound objects from another database system Where you have many compound digital objects to migrate • Prepare the collection and the import files • Cross-walk metadata to Dublin Core • Configure the CONTENTdm collection fields • Configure folders for scans and transcripts (if appropriate) • Choose an import method based on your data structure • Create tab-delimited ASCII file(s) appropriate to the method • Import the files to CONTENTdm in batches

  17. Multiple compound object wizard • Documented in online tutorial • Today’s demo described in handout • Four import methods for multiple object loading • Compound object (same as single, but upload batched) • Directory Structure (most flexible and efficient) • Object List (useful when NO page-level metadata) • Job List • Time allowing, demonstrate three different object types using 3 of 4 methods

  18. Choose a multiple compound import method based on your data

  19. Are your scan files Create compound object separated into No directories for EACH compound object compound object. directories? Yes Break up into batches by type Are they all the same type of compound No object? Yes Do you have one tab-delimited text file containing ALL the objects? Create text file listing all Do you have page-level Do you have tab- compound objects and metadata for the No No delimited text files for No object metadata or compound objects? EACH compound object? create a text file for each compound object. Yes Yes Yes . DIRECTORY STRUCTURE DIRECTORY STRUCTURE OBJECTLIST .

  20. Every one of the four CONTENTdm compound object importing methods • Requires object-level metadata • Requires preparation • File–naming, keeping sort order in mind • Each object has own directory for scans • May use tab-delimited text file(s) • Accommodates transcripts

  21. A word about descriptive page-level metadata • Supported by some but not all 4 import methods • NOT supported by Object List • At page-level Title is only field required • Technical metadata, can be generated by Template creator

  22. More on transcripts • Typescripts and transcripts • Requires a field designated as the data type “Full Text Search” • Inserted into the metadata field of the scanned page • During import • Through use of .txt file found, or • By Template Creator • If OCR Extension in use • Or by “Directory Import” as with early versions of CONTENTdm • Transcripts and typescripts are supported by all four methods (i.e., not considered “metadata” for purposes of this discussion)

  23. Demo: Import Multiple Compound Objects • Monograph using Compound Object method • Postcards using Object List method • Documents using Directory Structure method

  24. II. Exporting from CONTENTdm • To ascii tab-delimited with field headers • To xml: • Standard Dublin Core —only DC • Custom—all fields, including local but not structure • CDM Standard—all fields, including structure

  25. III. Examples of collaboration for interoperability • Web integration through search engines, RSS • OAI harvesting • Enable at collection or server level • Choose to suppress <pagedata> or not • WorldCat registration • Open WorldCat integration

  26. CONTENTdm and a new METS transform • Info available on USC in July • Code at SourceForge • Windows-oriented

  27. The CONTENTdm to METS conversion tool

  28. What is/are METS? Why is/are METS good? What is 7train? How do I use 7train? What do I get from 7train? How do I get 7train?

  29. What is/are METS? METS (Metadata Encoding and Transmission Standard) is an XML-based standard for encoding metadata to describe objects (digital or otherwise) within a digital library. See http://www.loc.gov/standards/mets/ for more information

  30. METS METS Metadata about this particular METS - encoder, contact info, etc. metsHdr metsHdr Descriptive metadata - title, author, subjects, etc. dmdSec dmdSec Metadata for the management of the object: technical details, object history, etc. amdSec amdSec A list of files that make up the object fileSec fileSec Description of the structure of the object, i.e. how the files fit together structMap structMap What to do with the object: machine actionable instructions behaviorSec behaviorSec Yellow elements/tags are required; all others are optional What is/are METS?

  31. Why METS? To be able to add your objects to other collections and increase the visibility your institution's assets.

  32. What is 7train? 7train is an XSL-based tool for converting XML documents - in this case CONTENTdm exports describing objects managed in the CONTENTdm system - into METS objects suitable for submission to a digital library system, such as the California Digital Library's Online Archive of California. 7train is a platform-independent, standalone tool that was designed to work on any system and to be simple to use.

  33. How does 7train work? It is as easy as dragging your CONTENTdm XML export file onto an executable file.
