Resource Manager

The Resource Manager (RM) is responsible for handling several functions centred around external resources. The RM supports connection to external resources through the maintenance of a persistent URL, and by allowing deep linking to the resources. It allows for searching of the resources using a variety of different protocols, and also has an administrative interface to allow for updating of metadata and to obtain usage statistics. The basic structure of the RM is a central metadata relational database that will contain all the information necessary to mediate access to external resources.

OAI Compliance

The ANGEL RM is compliant with the OAI repository standard. The links below demonstrate the following areas:

1. Identify: retrieves information about a repository.
   <http://bungo.lse.ac.uk/steve/cgi-bin/oai_interface_v0.6.pl?verb=Identify>
2. List metadata formats: retrieves the metadata formats available from a repository (as URIs of the XML namespaces of the format).
   <http://bungo.lse.ac.uk/steve/cgi-bin/oai_interface_v0.6.pl?verb=ListMetadataFormats>
3. Get record: retrieves an individual metadata record from the repository.
   <http://bungo.lse.ac.uk/steve/cgi-bin/oai_interface_v0.6.pl?verb=GetRecord&identifier=514&metadataPrefix=oai_dc>
4. List identifiers: abbreviated version of list records, retrieving only headers rather than full records.
   <http://bungo.lse.ac.uk/steve/cgi-bin/oai_interface_v0.6.pl?verb=ListIdentifiers&metadataPrefix=oai_dc>
5. List records: harvests the records (will accept a date stamp as an argument).

User Manager

The User Manager handles users of the Angel system. It allows users to log in to the system, provides authentication of the user and delivers authorisation details to the user thereby allowing them the rights to access the appropriate resources. Each Angel system is intended to be an individual service to users of a particular institution. The UM enables easier portability to further institutions that wish to adopt it as a solution. The Angel User Manager (UM) queries one or more institutional services to obtain user verification and directory data, presenting it in a unified format. This allows the main Angel software to treat any local user information in the same way, disguising all the technical and organisational idiosyncrasies. The main advantage to end-users of this approach is that once logged in to the Angel system there is no further need for them to enter username/password combinations to access resources controlled by Angel, such as libraries, content repositories and so on. They don't have to learn (or write down, insecurely) yet another password for each new service that the institution creates or connects to.

Scheduled Services Manager

The Scheduled Services Manager (SSM) will allow users to schedule automatic functions and tasks, such as scheduling of current awareness alerts, and keyword searching. The SSM will essentially take the form of a similar database to the RM, providing an interface for users to define tasks, and managing the scheduled services.

The SSM was specified in the ANGEL software development plan.  

DELIVER Smart Link Finder

The DELIVER Smart Link Finder is a tool for building and maintaining simple reading lists.  It includes a Universal Harvesting Tool (UHT) to allow users to simply and quickly add resource to URLs to course pages, and for these URLs to be supported via a central database.  In order to allow the UHT tool to use SmartLinks it must be configured to communicate with its own UHT database and an instance of the Angel Resource Manager.
