ArchivesSpace (or ASpace for short) is a server whose main purpose is to host a software program also named… ArchivesSpace. The program is “an open source archives information management application for managing and providing web access to archives, manuscripts and digital objects”. The server also hosts a few auxiliary programs who take the output from ArchivesSpace and convert it into various other formats, which are then made available via an Apache webserver on the same machine.

Background

We store digital descriptions of our archival collections in the following six places:

Workflow

• Finding aids are stored as Word documents at Shared/P/Othmer Library/Archives/Collections Inventories/Archival Finding Aids and Box Lists.

• Kent enters the data in them, one by one, into ArchivesSpace. He revises them in the process. As of summer 2020 approximately 45 have been entered.

• Once they are in ArchivesSpace:

  • They are automatically exported by https://chemheritage.atlassian.net/wiki/spaces/HDCSD/pages/2151514113/export+archivesspace+xml to EAD files at http://ead.sciencehistory.org/

  • They are also converted to HTML. Examples: Wotiz; Simon; Fenn; Carbogel; Brody. There is currently no Web page that lists these HTML files, so you have to know the URL beforehand or be directed to them from e.g. Google or the OPAC.

  • Kent also exports them to a PDF, which he then sends to Caroline. These are entered into the OPAC. (see e.g. https://othmerlib.sciencehistory.org/articles/1065801.15134/1.PDF )

    • Note: the PDF has to be manually updated in the OPAC every time the metadata in ArchivesSpace changes.

  • In certain cases the OPAC record also points at the HTML file at https://archives.sciencehistory.org/ .

  • Certain works in the Digital Collections also point to these HTML files.

• Finally, the exported EAD files are also ingested by University of Penn Libraries Special Collections and the Center for the History of Science, Technology, and Medicine (CHSTM).

  • Penn, in turn, processes these EAD files on a nightly basis and adds them to the Philadelphia Area Archives Research Portal (PAARP), a service funded by PACSCL.

    • Example: http://dla.library.upenn.edu/dla/pacscl/detail.html?id=PACSCL_SCIHIST_2012021USpaphchf

• Likewise, CHSTM ingests these EADs and makes them searchable at its search portal.

  • Example https://www.chstm.org/collections/search?text=Carbogel

• Note that external links to our HTML finding aids are rare and can be disregarded. There should be no need to provide redirects to these URLS when we eliminate them.

Technical details about the server

ArchivesSpace lives on an AWS S3 server ArchivesSpace-prod, at https://50.16.132.240/ (also found at https://archives.sciencehistory.org)

The current production version of Aspace is 3.0.1 .

Terminal access: ssh -i /path/to/production/pem_file.pem ubuntu@50.16.132.240

The ubuntu user owns all the admin scripts.

The relevant Ansible role is: /roles/archivesspace/ in the ansible-inventory codebase.

SSL is based on the following: http://www.rubydoc.info/github/archivesspace/archivesspace

The executables are at /opt/archivesspace/

The configuration file is /opt/archivesspace/config/config.rb
Logs are at: logs/archivesspace.out

Apache server is at /var/log/apache2/

Configuration for the Apache site is at /etc/apache2/sites-available/000-default.conf.

Main users

• Kenton Jaehnig

• Sarah Newhouse

• Patrick Shea

• Birch Mezzaroba (intern)

• Patrick Burden (intern)

Startup

• To start Archivesspace:

  • /opt/archivesspace/archivesspace.sh start (as user ubuntu)

• There may be a short delay as the server re-indexes data.

Restarting the server to fix Tomcat memory leak

We restart the ArchivesSpace program (not the server) using a cronjob that runs /opt/archivesspace/archivesspace.sh restart every night at 2 am. This prevents a chronic memory leak from eating up all the CPU credits for the machine.

When the server is restarted, Jetty creates a set of temporary files in /tmp

that look like this:

hsperfdata_ubuntu
jetty-0.0.0.0-8089-backend.war-_-any-3200460420275417425
jetty-0.0.0.0-8090-solr.war--any-_1669707332158985985
jetty-0.0.0.0-8091-indexer.war-_aspace-indexer-any-3026688914663148716
jetty-0.0.0.0-8080-frontend.war--any-3028692540497613460
jetty-0.0.0.0-8081-public.war--any-268053434795494538
jetty-0.0.0.0-8082-oai.war--any-_243630232179303838

Only the most recent set are used by Jetty, but the old ones accumulate rapidly if the server is restarted nightly.

A cron job removes obsolete ones nightly.

Export

The ArchivesSpace EADs are harvested by:

Both institutions harvest the EADs by automatically scraping http://ead.sciencehistory.org/.

Building the server

The server not yet fully ansible-ized.

What is missing from the ansible build:

• The build doesn’t copy the scripts in /home/ubuntu over correctly. Passwords for the scripts also need to be provided.

• All these directories under /var/www/html/ are also missing: css; ead; font-awesome-4.7.0; fonts; img; js.

• The ubuntu user needs to be added to the www-data group

• SSH keys are not loaded into /etc/ssl/private/

• The archivesspace server is not actually started (sudo systemctl start archivesspace).

Backups

These consist of making backups of the sql database used by the ArchivesSpace program.

See Backups and Recovery (Historical notes) for a discussion of how the chf-hydra-backup s3 bucket is then copied to Dubnium and in-house storage.

Restoring from backup

You can get a recent backup of the database at https://s3.console.aws.amazon.com/s3/object/chf-hydra-backup/Aspace/aspace-backup.sql

Note that the create_aspace.yml playbook creates a minimal, basically empty aspace database with no actual archival data in it.

To restore from such a backup onto a freshly-created ArchivesSpace server,

• copy your backup database to an arbitrary location on the new server

• ssh in to the new server

• Log into the empty archivesspace database:

  • mysql archivesspace --password='the_archivessace_database_password' --user=the_user

• Once at the mysql command prompt, load the database:

  • mysql> \. /path/to/your/aspace-backup.sql
