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!

Office with window

Potential liaison role interview practical exercise

Somewhere not much under twelve months ago I discovered this office being used as a storage dump. Meanwhile I was working down in the basement, round the back of the rolling stack, with a view of some aircon fans.

I think getting yourself moved from a basement to a rather nice spot would make a pretty good practical exercise when looking to recruit new library liaisons.  Admittedly it would take a bit longer than the normal five minute presentation but I guarantee anyone who can achieve this task is likely to be worth having around. You could ask people how they might go about progressing this? Who they would speak to? How they might make the case and persuade people to their point of view?

Time to unpack!

#buildalibrarian run complete but still open

Last Sunday saw me complete the run part of #buildalibrarian.


After Hoohaah race

On a personal level I was very pleased with a time of 52 minutes 11 seconds which was miles inside my previous best (and triggered some extra performance related money!).

Fund raising wise I have gone well beyond what I hoped.  At the time of typing there is over six hundred pounds on the totaliser even without the gift aid. The Just Giving site will stay active for another three months so there is still time for a bit more money to trickle in.  I have already updated it with some before and after pics.  There will be terrible red faced action shots worse than the above for kind supporters.

I hope to update in future about Partnerships in Health Information – have a look at their spiffy new website!

A hoohaah for Partnerships in Health Information #buildalibrarian

Partnerships in Health Information is a small charity I have supported for a number of years.  They work with African libraries to build capacity, support evidence based practice and improve public access to health information.

Last year I spent the morning exchanging knowledge with two Tanzanian librarians who had been hosted by PHI as Commonwealth Professional Fellows for a three month study tour in the UK.  It was a great reminder of the valuable work PHI do. I was also prompted by a tweet about #buyalibrary from a couple of years back. I hope people will be as keen to #buildalibrarian

I have registered to run in the Hoohaah run on the 21st of June. There is 10k to cover with a bit more by way of gradient than I am used to so it should be reasonably hard work.

I am using JustGiving as PHI have an account with them and as a very small charity this is a very effective way to get money to them.  I am not a great runner by any means – lumbering of foot and red of face.  You can track my early morning efforts on Endomondo if you want to be sure I am not slacking off.

If you can give a little something that would be great. Even better would be if you could give a little something and share what I am trying to do ( Or just share!
