User Guides

log_dip

The command log_dip is intended for use by BDRC staff to instrument their publication activities. log_dip takes arguments from the shell and transfers them into a database table.

log_dip --help

  -r ACTIVITY_RETURN_CODE, --activity_return_code ACTIVITY_RETURN_CODE
                        Integer result of operation.
  -b BEGIN_TIME, --begin_time BEGIN_TIME
                        time of beginning - ')yyyy-mm-dd hh:mm:ss bash format date +'%Y-%m-%d
                        %R:%S'
  -e END_TIME, --end_time END_TIME
                        time of end.Default is invocation time. yyyy-mm-dd hh:mm:ss bash format
                        date + '%Y-%m-%d %R:%S'
  -c COMMENT, --comment COMMENT
                        Any text up to 4GB in length

                        Destination path (optional) - string
  -L, --resolve-sym-links
                        True to resolve file paths, false to accept input as is
  -n INVENTORY, --inventory INVENTORY
                        path to inventory (only used for ARCHIVE)

Argument structure

log_dip creates a database record that captures the beginning or end of a DIP event.

All its operations return an opaque identifier which can reference the record. In bash, this would be invoked as

You reference the record later by one of two methods:

• passing in the id from the initial (or subsequent calls):

dip_id=$(dip_log --drsDbConfig sec:some.config --begin_time "2021-05-11 01:23:45" --activity_type DRS --work_name W12345)

dip_log -d sec:some.config --activity_return_code 42 --end_time "2021-05-11 12:34:56" --dip_id $dip_id

• using the work Id, Activity type and begin time:

dip_log -d sec:some.config -b "2021-05-11 01:23:45" -a DRS -w W12345

dip_log -d sec:some.config -b "2021-05-11 01:23:45" -a DRS -w W12345 -r 42 -e "2021-05-11 12:34:56"

Both of the above examples perform the same function:

1. log the start of a DRS job for work W12345 at “2021-05-11 01:23:45”

2. log the end_time of the job at “2021-05-11 12:34:56” , with a return code of 42

Argument hints

• to give an end time, you must give all the job id information, either in the id, or with the (work_name, begin_time, activity_id) tuple

• You can add as much information as you want in one call. If you’ve captured the begin time, you can create a call which logs them all at the same time (this is not the best practice, because it eliminates the system’s ability to check for in-progress jobs). This is perfectly legal:

dip_log -d sec:some.config -b "2021-05-11 01:23:45" -a DRS -w W12345  -r 42 -e "2021-05-11 12:34:56 -c "Hi Mom, Im re-writing history"

• Begin and end dates are fussy: in shell, the format for generating the date dip_log requires is: date +%Y-%m-%d %R:%S (for Mac with GNU core, GNU Linuxes)

• you can update some DIP log properties:

  • comments

  • end time

  • operation return code

• Obviously, since these are the tuple which identifies the transaction, you cannot modify:

  • work name

  • begin time

  • activity type

  • dip_external_id (this is a read only argument supplied by the caller of log_dip)

In this example, the comments field is updated.

dip_log_id=$( dip_log -d sec:some.config -b "2021-05-11 01:23:45" -a DRS -w W12345  -r 42 -e "2021-05-11 12:34:56 -c "Experienced some discomfort")
dip_log -d sec:some.config -i $dip_log_id  -c "But it passed.")

• Any property not given in the command line is preserved. (The example above preserves the begin and end times of the DIP transaction.)

• the comment field is a free-form text field of up to 4GB in length. You can store XML or JSON data in it for later use. (such as any error messages or summary information about the process or the objects being processed). Update: the deep-archive utility reads the comment field for coded data.

Deep Archive and Inversion

Inversion

In version 1.0.2 of bdrc-util the deep-archive utility was created, to send to Glacier Deep Archive separate image groups. This allowed large works to be sent as separate smaller segments. (It also allowed other material that was not categorized by image group to be sent to Glacier.) The process packages all the media types (sources, archive, images) for an image group into one bagged zip file.

Sync and Deep Archive

archive-ops-1087 - sync by image group specifies enhancements to the sync process to sync fragments of image groups. README.md documents these requirements and provides examples.

API

A simple API, inspired by openpecha.buda.api is provided as a central library for commonly used utilities, including Legacy Hack Image Group Translation
