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!

Well beyond our walls at UHMLG18

My first attendance at a UHMLG Spring Forum was a positive experience with some inspiring talks that very much appealed to my desire to see positive work by health libraries in the world.

The presentations are available.  The one closest to interests at work was given by Antony Brewerton on what University of Warwick Library are doing around student wellbeing.  This is an important agenda across HE and the NHS and the scope and impact of their work was inspiring.  Recognising the needs of our students and addressing them in ways that drive engagement and create community is so positive.  I loved the idea of free fruit in exchange for sharing a revision tip.  The idea of hosting events related to some of the international students cultures was also a great way to help different student communities meet and address the feeling of being far from home.

I was also very interested to hear about the work of Evidence Aid.  This sounded quite a commitment time wise but with the potential to make a serious difference to workers out in the field.

A key message that came through the various talks looking at partnerships and projects in Low and Middle Income Countries was the imperative to have proper contact with the people on the ground.  This stands for all our interactions with library users (and non-users) where we need to be talking to them to understand what they need and where we might best make a difference.

The day closed with some lightning talks.  I would love to see an integrated membership form in our LMS as it could really free up time of the front of house team.  The Expo stage in the new Royal College of Surgeons of Ireland Library also presented a model for driving ownership and community.

I was one of the tweeting team for the day which I found fitted fairly well around the level of notes I would normally take.  I think I was probably too literal in my reporting some times but hopefully the links I added would have been helpful.

Some random nice extras were the recognition for Betsy Anagnostelis on her retirement and a bottle of champagne I won from one of the supplier stands!  A well organised and useful day. I hope to attend others.

Hum – just found this in draft – oops!

Update Feb 2016 (and Dec / Jan 2016)

So the old model of trying to work through the old issues was failing. New plan – the current issue plus most recent back issue with the new issue as the trigger to get it done. This should mean things are more current but I will probably write a bit less to get through them.

Dec 2015 / Jan 2016 first!

MyLibraryMyRight is an about time moment. Progress has been slow on the petition but I suspect this will be lower impact than some of the other measures. No action means the end of the public library service as the squeeze on local government operates to grimly collapse things.

The failure of the obligatory revalidation change to be voted through gets a small mention. The recent analysis released of patterns of voting seems to indicate it was mostly rejected by those later in their careers and in public libraries (not clear if these features intersect). Depressing.

A chunky Knowledge for Healthcare update. The scale of work underway is quite daunting and it is remarkable that work can be carried out England wide to this extent. Some great people on the leadership development programme and it will be great to see the projects that emerge from this.

Having had a chat about zines today at work I enjoyed the article on a workshop on these as part of the fun palaces initiative (which sound great – I wonder if we could have a fun palace at work next year though timing is not great for the academic year). A library zine might be a way to cut through some of the formality that tends to take over away from our social media communications.

Feb 2016

The cover story on a library in North Darfur was great. Such a positive piece of work and a recognition that libraries are about a lot more than books. 

The growth of content on the CILIP VLE is encouraging as a means for people to access CPD opportunities. I will have to have a rummage when I next go in to revalidate.

Service Transformation this issue from Knowledge for Healthcare. A challenge for me is how to respond to this work in the very different setting of an academic library that also serves the NHS. Very real change will be required for us to deliver on the KM and current awareness agendas. Document supply we sit largely outside the NHS schemes – could we export some of how we work at scale?

The Social Policy and Practice database sounds a useful resource. It isn’t in the national core content for NHS staff though I could see if being useful for a good number of people.
