    Preparations for Creating a Plan

    A Preservation plan is based on preparatory work performed in the format library and risk analysis segments of Rosetta. The foundations of this work center on establishing a comprehensive format library and identifying the risks that accompany each format in the library, then creating queries and sets of objects that belong to those formats and risks.
    For detailed information on how to develop these building blocks, see the sections on format libraries and risk analysis in this guide.

    Building a Preservation Plan

    You can build a Preservation plan based on a Preservation set or a duplicate of an existing Preservation plan. Additional key components include alternatives (distinct paths or treatments of at-risk objects) and evaluation criteria for those alternatives.

    A Plan from a Preservation Set

    You can perform searches of objects in your repository based on at-risk formats. The results will help you determine the degree of risk that exists among objects in your collections.
    To build a plan from your risk format results, perform the following steps.
    1. With your risk results open on the Search Object page, click the Launch Advanced Plan button.

    1. Click the check boxes beside the users to which you want to assign the evaluation. Then click the Add button.
      The Plan Details - Evaluation Assignment page refreshes with the user(s) you selected.
    2. Click the Save button to save the plan and return to the List of Preservation Plans page. To save the plan and go directly to the Alternative List, click the Alternative List button.

    Evaluation Criteria

    The evaluation criteria of preservation plans and plan alternatives can be customized to suit your institution’s needs and priorities. Fields for evaluating criteria can be added to the system. They can be classified by type (text field or drop-down box). Code tables for drop-down values can be created by staff and stored in a dedicated table. This table and all related code tables are accessible to Preservation Analysts and Managers through the Management > Preservation user interface. Analysts creating evaluation forms for plans and alternatives can draw from this pool of criteria, as needed.

    Managing Plan and Alternative Evaluation Forms

    Evaluation criteria is set up for plans and plan alternatives in the same way.
    You must first connect to the consortium before making code table updates for preservation.
    To set up evaluation criteria:
    1. Follow the path from the Preservation tab to Advanced Preservation Activities to Plan Evaluation Criteria or Alternative Evaluation Criteria, depending on whether you are developing criteria by which to evaluate a plan or to evaluate an alternate to a plan.
      The Manage Evaluation Criteria page you selected opens.
    Evaluation Criteria Page.png
    Evaluation Criteria Page

    Existing fields and information for each field display in a table.

    Header Information
    Field Name The label of the field as it appears on the user interface of the person creating the survey.
    Description The tooltip, typically directions for how to enter a value for the field.
    Field Type The type of value, indicating the way to enter the value (select drop-down or enter text). Drop-downs (or “Combo Boxes” must be accompanied by code tables listing available selections.
    Code Table Name The code table that lists values for a Combo Box field. This table can be added to the system, or an existing code table can be used, with or without edits. See

    Fields can be added (button top left), edited, or deleted (per row).

    1. To view a field in detail and perform edits, click the Edit link of the field’s row.

    View or Edit Entries for an Evaluation Field
    1. Add entries for a new field or edit existing entries.
    2. If you are creating a “Combo Box” (or, a box displaying values that the customer much choose from), click either the Edit Table button or the Create Table button to edit or create values for the selection box. See Adding/Editing a Code Table for information on how to manage code values for an evaluation field.
    3. If you are creating or editing a text field, select the Field Type of Text.
    4. When you are finished entering fields and values for the evaluation field, click Save to save your edits/entries and return to the list of fields for your plan or alternate.

    Adding/Editing a Code Table

    You must first connect to the consortium before making code table updates for preservation.
    To add or edit values for a drop-down list within a field:
    1. Click the Create Table button or, to edit an existing table’s values, select the Code Table Name from the drop-down menu and then click the Edit Table button.
      The Code Tables page opens.
      If you are creating a new table, enter a name and description in the respective fields and click the Create button. The empty row for a code table opens below the general table information.
      If you are editing an existing table, the full Code Tables page opens with values entered for the field you selected.

    To switch to another table, click the Table Name drop-down list and select a different table name.

    1. Edit any existing row or add a new row from the Create a New Code Table Row section. You can also change the display order of the values as they appear in the drop-down list by clicking the up or down arrow buttons in the Display Order column.
    2. When you have created the new table, click the Save button.
      The new or edited code table is saved to the system and can be used as part of an evaluation criterion,is added to the Preservation Plan, and shows in all future Preservation Plans and Plan Alternatives.

    Adding Plan Alternatives

    A plan alternative defines, for a format risk, a possible path, its actions, and its outcome for mitigating the risks of that format. More than one alternative can be assigned to a single format risk, and a Preservation Analyst can determine which option is the most beneficial to the institution based on tests of the alternatives (and other considerations).
    Alternatives involve converting existing objects so that they become viable for the future, using either an internal plug-in tool or an external service. Every Preservation plan requires at least one alternative plan. This allows the institution at least two options when evaluating the plan: to keep the data as it is (in its source format) or to perform an alternative action to improve the quality and/or longevity of the data (in a target format).
    To create an alternative for a plan:
    1. Access the Alternatives Details - General Information page through one of the following paths:
      • After creating a plan, click the Alternative List button at the bottom of the Plan Details - Evaluation Assignment page.
      • From the Preservation main page, click Preservation Plans, then click the Alternatives List text link corresponding to the row containing the plan you want to work with.
        The first time the Alternatives List Page is opened for this plan, no alternatives are listed and the message. No records were found displays below the Add Alternative button. Once you have added alternatives, Rosetta lists them in a table below the Add Alternative button.

        Alternatives List, Two Existing Entries
        When alternatives have been added, they appear in a table with general information and available actions (detailed below).
        Fields and Actions on the List of Alternatives
        Field Description
        Add Alternative Adds a new alternative for the plan. Note that the only supported alternative type at this point is migration.
        Evaluate Test Opens the evaluation interface for evaluating the test results.
        View Opens the alternative in view mode.
        Handle Technical Issues Opens the TA folders where failed test sets are stored.
        Test Summary If the alternative has been tested, opens the test results summary.
        Edit Enables the user to edit the alternative details (selected plug-in, evaluation criteria, alternative evaluation).
        Duplicate Creates a duplicate of the alternative.
        Delete Deletes the alternative.
        Run Test Runs a new test of the plug-in on the test subset. The system creates a new test record and directs the user to the test list. In the case of an external migration alternative, this action launches the process of creating the descriptor file and separates the representations that need to be sent for migration outside of Rosetta.
        Import For external migration alternatives, this action launches the automatic validation that checks the descriptor file and matches it with the number of files in the import directory. If the validation passes, the loading starts automatically. If the validation fails, an error message specifies the lines in the descriptor file that didn’t pass the validation.
    1. To create an alternative, click the Add Alternative button below the general information pane.
      The Alternatives Details wizard opens. The top pane contains general information like the plan name, the source classification and format, and the creator of the plan.

    Add Alternative Wizard, Step 1 - Migration Type External

    Add Alternative Wizard, Step 1 - Internal.png

    Add Alternative Wizard, Step 1 - Migration Type Internal
    1. Enter information in the fields according to the table below.
       Alternative Wizard Step 1 Fields
      Field Description
      Alternative Name The name of the plan alternative.
      Description (Optional.) A description of the actions involved in this alternative.
      Target Format The format to which the source files' common significant properties should be automatically compared. The drop-down opens a list of available formats in the Format Library.
      The actual migration target format depends on the selected migration tool.
      Migration Type Either internal or external, depending on whether the migrations in the file use an internal plug-in tool and are carried out through the Rosetta process automation framework or whether the files are sent to an external vendor who converts the files off-site and returns them to Rosetta as new representations of the IEs.
      Select Plug-in A field that displays after a user selects Internal for the Migration Type. The field contains a drop-down list of all plug-ins that work with the selected format.
      Export/Import Directory When the user has set the Migration Type to external, read-only directory paths for outgoing files (Export Directory) and returning files (Import Directory) display below the Migration Type field.
    2. Click the Next button.
      • If the plug-in requires parameters, the second step of the wizard opens with a place for those parameter values below the Plugin Parameters bar.
        1. Enter values in the Plugin Parameters section.
        2. Click the Next button. The evaluation criteria for the alternative opens as step 3.
      • If no plug-in parameters are required, the evaluation criteria for the alternative opens as step 2.
    Alternative Wizard, Step 3a.png
    Alternative Wizard, Step 2

    Four types of evaluation, based on the format source and target for the alternative, display on this page.

    Alternative Wizard, Step 3
    Type Description
    Automatic Evaluation - Source vs. Target The user selects the properties of the classification group that should be measured by the system when it compares the original format file to the migrated file (for example, File extension must equal file extension).
    Automatic Evaluation - Target Characteristics only The user selects the target file properties that are not compared to those of the original file, but are measured according to the selected operators and parameters (for example, File size smaller or equal 3MB). Select Validate Format ID to validate the target's file format (as selected in the first step of the alternative wizard) and inform the user when viewing the plan results if conversion succeeded or not.
    Automatic Evaluation – File Comparison Plugin The user selects a plugin, an operator, and a parameter to define the criteria for comparing the files.
    Manual Evaluation The user selects the evaluation criteria that are stored in a separate table with their possible values. For example, the criterion Character -> Font size unchanged could be Yes or No. The evaluation criteria is stored in the Evaluation Criteria Mapping table, which holds the name, description, and controlled list of values if the criterion is a drop-down. For more information about configuring this table, see the Rosetta Configuration Guide, Working with Mapping Tables.
    1. Use the drop-down menus and text fields to indicate parameters for automatically evaluating the alternative source compared to the target or the target on its own.
    2. Add or remove any manual criteria using the Add buttons and Delete text in the bottom section (Manual Evaluation) of the page.
    3. Click the Next button.
      The Alternatives Details - Evaluation Criteria page opens. This is the final step of the alternatives wizard.
    Alternative Wizard, Step 4.png
    Alternative Wizard, Step 3

    All the criteria selected previously by the plan editor displays for the evaluator. Each criterion has a list of possible values for selection (for example, Yes/No, Good/Fair/Bad) or an open text box for writing an evaluation.

    1. Enter the details and click the Save button
      The alternative is complete and Rosetta returns you to the Alternatives List page, where the new alternative appears as an entry in the table.

    Editing Alternatives

    Users can edit existing plan alternatives at certain test stages (when the alternative isn’t being actively tested).
    To edit an alternative for a Preservation plan, open the Alternative Details page by following Preservation > List of Preservation Plans and clicking the Alternatives List text link corresponding to the plan’s row, then the Edit link corresponding to the individual alternative plan.
    The Alternatives Details page opens to the General Details tab.
    alternative_details_edit_page.png
    Alternative Details Edit Page
    Each tab corresponds to a different kind of information. (This information was entered initially through the Add Alternative wizard.)
    For more information on the fields, see Adding Plan Alternatives.
    For information relating to the testing and execution of plans, see Adding Alternatives.

    Descriptor File

    The descriptor file is relevant for an external migration only. It holds information on the files, representations, and IEs used to create new representation(s). This section describes descriptor file

    Generation

    The descriptor file is used both for export and import. It is generated differently according to the source of the add representation action.
    When the user clicks Execute on a signed-off Preservation plan, the system creates the descriptor file. All the fields in the Add Representation Fields mapping table are mapped in the descriptor file. While processing each IE in the set, the information on the original IE, the representation, and the files are added to the descriptor. For each file, the indication of whether conversion is needed or not will be added to the descriptor.
    The descriptor file is updated outside of the system, either by the vendor performing the conversion or the library staff. When the files are imported, an updated version of the descriptor is also imported.

    Contents

    The descriptor is a comma-separated values (CSV) file. The first line in the descriptor will contain the column names.
    The following fields in the descriptor file are required:
    Required Fields in the Descriptor File
    Field Name Description
    IE PID The PID of the IE to which the new representation must be linked.
    Representation PID The PID of the original representation. The value is recorded in the descriptor during export. This value will be used later in the import process (for Provenance Information).
    Preservation Type The Preservation Type of the original representation, Preservation Master or Modified Master. For Preservation actions, the type is created during export and the same value will be used for import. The new representation will be assigned the same Preservation Type as the original representation. For representations added from the Web Editor, the Preservation Type will be taken from the value the Editor enters in the form. This column will be mapped to the field DNX.generalRepCharacteristics.preservationType.
    Original PID The PID of the original file. It is created during export. This value will be used later in the import process (for Provenance Information).
    File Name The name of the original file will be inserted during export. When importing, the name has to be replaced by the name of the new file.
    File Location The path to the file relative to the directory where the descriptor file is placed.
    Usage Type The Usage Type of the original representation. For Preservation actions, it is created during export. This value will be used later in the import process. The new representation will be assigned the same Usage Type as the original representation. For representations added from the Web Editor, the Usage Type will be taken from the value the Editor enters in the form. This column will be mapped to the field DNX.generalRepCharacteristics.usageType.
    Conversion Required When adding a representation, the user must provide all the files for the representation. When exporting, all the files will be exported. It is possible that only part of the files need conversion. For this purpose, for the files that need to be converted, the value of this field will be “Yes,” for files that don’t need conversion, the value of this field will be “No.”
    Submission Reason This field will appear only for Master representations. The field will be filled in only when Add Representation is called from the Web Editor (that is, no Preservation plan is attached). The text entered will be saved as a Provenance event.
    It is possible to define a dynamic list of DNX fields to load when adding a representation.
    In order to support the dynamic definition of metadata fields, the mapping table Add Representation Fields is provided. The mapping table defines which DNX field each of the entered values is mapped to. All the fields listed in the Add Representation Fields mapping table can be added to the descriptor (for example, Label, Representation Code, Mime type, File Label, Checksum, Capture System, Source Type).
    • When a new representation is created, a generic structure map is created and the original physical map is abandoned. The system does not support adding a new logical structure map through the descriptor.csv file. The physical structure map will be generated according to the order of the files in the descriptor file.
    • There are two separate descriptor files, one for export and one for import. The format of the files is the same. The two files are placed in the same directory.

    Validation

    Before importing the files, the system performs a series of validation tasks, ensuring that:
    • The descriptor file format is correct: it is a.csv file. If an error is found, a message will be displayed and the Add Representation process aborted.
    • The number of files in the Import Directory matches the number of files in the descriptor. If an error is found, a message will be displayed and the Add Representation process aborted.
    • The names of the files in the Import Directory match the names of the files in the descriptor. There are no extra or missing files.
      • When adding a representation from the Web Editor, if an error is found, a message will be displayed and the Add Representation process aborted.
      • When adding a representation as part of a Preservation Test or Execution, if files are missing for an IE, the IE will be marked as a candidate to skip and Add Representation will continue with the next IE. See Error Handling for more details.
    • The descriptor file is well-formed. If an error is found, a message will be displayed and the Add Representation process aborted.
    • The descriptor file contains all the mandatory fields. If an error is found, a message will be displayed and the Add Representation process aborted.
    • All the labels in the descriptor file match labels in the Add Representation Fields mapping table. If an error is found, a message will be displayed and the Add Representation process aborted.
    • The values of fields with object type representation (for example, Preservation Type, Representation Code, Usage Type, Capture System and Source Type) are the same for all the files in the same representation. If an error is found, a message will be displayed and the Add Representation process aborted.
