SIR: Semantic Instrument Repository

This repository has been developed as a custom module for Drupal 9+ and implemented mainly in PHP. The module depends on an external API called HASCOAPI (HASCOAPI code is available at https://github.com/HADatAc/hascoapi). SIR content is stored inside of the API's knowledge graph.

• Developer: HADatAc.org community (http://hadatac.org)

Deployment:

SIR deployment requires the availability of a Drupal instance (version 9 or above), and an user of this Drupal instance with adminstrative privileges.

• upload SIR code
  • in the admin menu, go to Extend > Add New Module > Add from a URL
  • paste the following link from github: https://github.com/HADatAc/sir/archive/refs/heads/main.zip
• upload module dependencies. See below a list of current SIR dependencies:
  • Key (https://www.drupal.org/project/key)
• go to Extend and install both SIR and its dependencies
• clear all Drupal caches
  • in the admin menu, go to Configuration > Performance > Clear All Caches

Configuration setup:

User needs to have administrative privileges on Drupal to be able to setup SIR

• Step 1: setup secret key to connect to API
  • the secret key is a string used during the setup of the API. The secret key of SIR and its API must be exactly the same
  • In SIR, the key is added going to [drupal_url]/admin/config/system/keys/add
  • Provide a name that will be later selected in the SIR configuration page
  • Select type Authentication
  • Select provider Configuration
• Step 2: setup SIR
  • go to Main Menu > Advanced > Configuration (or alternativelly [drupal_url]/admin/config/sir)
  • Check whether or not you want SIR search page to be the main page of your website
  • Provide a short name
  • Provide a full name - used as the website's title
  • Provide a domain URL - this is the base of the URIs for all the SIR elements created in the current SIR instance
  • Provide a namespace for the domain
  • Provide a description for the website
  • Provide the base URL for the API -- this is the URL of the back-end machine hosting the API
  • Provide the name of the key used to create API tokens -- the API is not going to respond if the token is missing or is incorrect
• Step 3: setup SIR's Knowledge Graph
  • go to Main Menu > Advanced > Configuration > Manage Namespaces (or alternativelly [drupal_url]/admin/config/sir/namespace)
  • verify that you can see a list of namespaces
  • for the namespaces with values for Source URL, verify if they have values for triples. If not, you need to select the Reload Triples From All Namespaces With URL
  • wait a while and press the refresh button of the browser to verify if the triples have been loaded
  • if needed, the triples can be deleted and reloaded again. Wait for the triples to be zeroed before reloading.

Usage:

Once the module is installed, SIR options are going to be available under main menu > Advanced. Access to SIR options depends on user permissions on Drupal. By default, an anonymous user of a SIR repository has access to the search and about pages.

Upgrade (in Pantheon):

• put website under maintenance (Configuration > Maintenance Mode > Put site into maintenance mode)
• using Drupal Admin Menu's Extend, uninstall SIR module
• clear caches
• using Pantheon's site maintenance, move website from git to sftp mode
• use sftp to remove module files under /code/web/modules
• use sftp to remove module files cached under /tmp
• clear caches
• using Extend, verify if SIR module's code has been removed from the list of available modules
• remove website from maintenance
• put website under maintenance
• using Extend, upload new version of SIR module
• using Extend, install new SIR
• clear caches
• remove website from maintenance
• restore sir configuration including key
