The NLH Enterprise Architecture – looking to the future

For a couple of years now I have had a copy of “An Enterprise Architecture for the National Library for Health: Direction of travel and deliverables” sat in my inbox.  At the time I was preparing a report considering HDAS (the NHS in England interface for searching literature databases) and I wanted to remind myself of the content of this dimly remembered document.  Linda Ferguson kindly dug it out (on a site since dead) and it has been sat nagging me ever since.

The version of the EA above dates from 2006.  I confess I failed to grasp the scope of the vision it represented at the time.  The language is by nature technical but the ambition is very clear.  A number of initiatives now under way in the NHS in England could be plucked directly from this document and would certainly be much easier to deliver if we had gone further down some of the paths it suggests.

The document lays out a plan for delivery of NHS Library web based services.  At the core is the need for “a set of interoperable, networked services that conform to appropriate open standards”.  This would be supported by various things such as shared schemas for meta data and a central registry for API specifications.

I want to consider how the implications anticipated at the time have worked out and where things might be going in the future.

There were several implications identified for national services

 

A coherent and integrated user journey is desired. Presentation layers, what the user sees as a web page and how results are presented, will be separate from content and services and owned and built by the NHS.

Procurement will focus on content and the necessary APIs to integrate content into the discovery and current awareness processes. Increasingly, we do not wish to purchase content locked into any single portal.

A core search service will index all NHS content. It too will have a SOA, providing the basis for search pages. It will integrate with related services such as link resolvers

An NHS resolver service will be a key component in the delivery process. The NHS will wish to procure and own a resolver solution as a managed service.

An NHS library– wide Access Management System is being procured. Use of this system will be mandated for information suppliers. It will be SAML compliant.

Much of this has come to pass though perhaps without the core search service.

HDAS has reasonably successfully allowed for changes to the suppliers of content (databases) without massively impacting the experience of searching for the end user.  The varying API offered by suppliers have not fully supported the consistent search experience desired and there have been performance issues.  What has not happened perhaps is the ongoing integration of other services such as document supply and support at the point of need into HDAS.

We have seen the procurement and integration into HDAS of different link resolving solutions.  OpenAthens has been a long standing partner for access management.

Looking to the future work is underway to deliver an NHS England wide discovery solution and how well this maintains control over the web page and presentation of results will be interesting.  This could potentially be the “core search service”?  NHS Evidence already does this job for some categories of materials but stays away from the literature databases that would swamp the materials it aims to present.

A missed opportunity was the investment to create an NHS England wide Library Management System based in one of the Open Source solutions.  A small central team could have administered and developed a tailored approach that would have matched some of the ambititions of the EA.  I suspect the overall cost over the past decade would have been significantly lower and the opportunities for creating a platform for services greater.

There were also implications flagged for local services

local e-content, whether procured or NHS generated can, by adhering to EA principles, be integrated with national content, either within NLH or within other portals.

New services can be built up around this technology. For example, local current awareness and alerting services can be integrated with national services to provide the user with one way of getting knowledge updates

A single NHS library-wide Access Management System provides web Single Sign-on linking library services to their user base and will provide a bridge to NHS SSO services, opening up library service to non-library users.

Generally we have been happily plugging in locally procured content into national systems.  A gap has been around a solution for ebooks and this will need to be addressed in any new discovery layer as this format grows in importance.  The ability to integrate local content will depend on standards and considering these might be an early priority (as fixing them later will be trickier).

Recent revisions to HLISD will hopefully have maintained the commitment to the important location and service information being available via API to build other service offers.  The wide adoption of KnowledgeShare raises questions of how this (or an equivalent) might be integrated into a future national digital service.

In an ideal world we would have single sign on using peoples Trust logins – any additional login (even one as familiar as OpenAthens) is an unwanted barrier so an NHS SSO is the right ultimate target.


So quite a lot progressed and quite a lot left to do.  As the NHS in England moves towards the procurement of a new discovery tool it feels to me more critical than ever that we maintain the drive of the NLH Enterprise Architecture for the delivery of “a set of interoperable, networked services that conform to appropriate open standards”.  What I would like to see more of is the role of the person supporting at the point of need within that networked service.

These are my views based on my involvement with various aspects of the health libraries system at different points.  I am very happy to be corrected on points of accuracy – and challenged on matters of opinion!

HILJ CPD reading Volume 35 No 3 – Developing a generic tool to routinely measure the impact of health libraries

Welcome to the second experimental online reading group aimed at encouraging discussion of interesting articles in HILJ.  The first attempt took place around Volume 35 No 2 on CILIP Social Link (link may require CILIP login and may not take you to the right place).  Unfortunately we found SocialLink did not really offer quite what was needed so future editions will rove across any ones blog that cares to host.

I raised the possibility of having a regular discussion on articles from HILJ at HLG2018 having muttered about it for some time and as others expressed an interest (in particular Lisa Burscheidt, Morag Clarkson, Catherine Mclaren and Tom Roper) here we are.

As an HLG Member you should have access to HILJ via the link below https://archive.cilip.org.uk/health-libraries-group/health-information-libraries-journal/access-health-information-libraries-journal-hilj though many have it in a Wiley bundle and that maybe easier! The article this time is OpenAccess anyway so should be straightforward.

The idea is that an article will be selected from each issue to be discussed. The group have picked an article but there might be a vote in future or we may carry on picking a favourite by some other means (perhaps the host blogger gets to choose). The intention is to select articles with practical applications. We will offer some questions as prompts but the discussion can go where interest takes it.

The article selected this time is:

Developing a generic tool to routinely measure the impact of health libraries

Abstract
Background

Health libraries contribute to many activities of a health care organisation. Impact assessment needs to capture that range of contributions.

Objectives

To develop and pilot a generic impact questionnaire that: (1) could be used routinely across all English NHS libraries; (2) built on previous impact surveys; and (3) was reliable and robust.

Methods

This collaborative project involved: (1) literature search; (2) analysis of current best practice and baseline survey of use of current tools and requirements; (3) drafting and piloting the questionnaire; and (4) analysis of the results, revision and plans for roll out.

Findings

The framework selected was the International Standard Methods And Procedures For Assessing The Impact Of Libraries (ISO 16439). The baseline survey (n = 136 library managers) showed that existing tools were not used, and impact assessment was variable. The generic questionnaire developed used a Critical Incident Technique. Analysis of the findings (n = 214 health staff and students), plus comparisons with previous impact studies indicated that the questionnaire should capture the impact for all types of health libraries.

Conclusions

The collaborative project successfully piloted a generic impact questionnaire that, subject to further validation, should apply to many types of health library and information services.


I picked this article as this has been a hot topic for some time now.  I expect many of us will have experience and views on the generic impact questionnaire so there should be useful discussion.  I have not read the article before selecting it!

Starter Questions –
What? What do you think of this article / the generic impact questionnaire / etc?
So what? Does this change your view of the tool?  What changes might we want to see with the tool?
Now what? Are you going to do anything with it?

The next edition of the HILJ CPD Reading experiment (name suggestions welcome! #HILJClub perhaps?) will appear when volume 35 no 4 appears and be hosted by Lisa Burscheidt over at That Black Book.

Look forward to the discussion!  The comments box is further down in this template than I realised so do scroll down to reach it!
