Mahendra Mahey, manager of British Library Labs (BL Labs) will examine some of the BL’s digital collections/data & discuss challenges he has had in making the BL's cultural heritage data available openly or onsite at the British Library.
Mahendra will invite delegates to explore data-sets at their leisure, setting a challenge for those who are interested, skilled in exploring, finding patterns and grouping data. They could become data-set authors/creators of derived data-sets, based on pre-existing digital collections/data provided on the day or already available on https://data.bl.uk.
The workshop will conclude with reflections from the delegates and possibly highlighting a number derived data-sets that were generated by participants on the day that could now potentially exist on https://data.bl.uk. If selected, these new derived data-sets will be attributed with the creators' / authors' details and each will have its own cite-able Digital Object Identifier (D.O.I). These new data-sets would then be available for reuse by any researcher in the world.
GUIDANCE FOR THIS WORKSHOP
We strongly recommend you come to this workshop with an appropriate device such as a laptop pre-installed with appropriate tools to analayse different kinds of data-sets, e.g. Microsoft Excel may work with smaller data-sets such as metadata (see other data exploration tools below). If you don't have one, and would still like to attend, please request to 'pair up' with someone who is willing to share and has already signed up.
Other data exploration tools include: Notepad++ (e.g. for viewing text and XML); Open Refine (e.g. for cleaning data); Tableau Public (e.g. for visualising data); Google Fusion Tables (e.g for visualising geo-spatial data); Spacy (e.g. for text and data mining), RStudio (an open source Statistical package), MATLAB (data analysis tool) & NLTK (Natural Language processing).
Please note that this workshop is NOT about training you in using any of these tools, just tools you may be already familiar with to explore and find patterns in our data.
Datatypes you may be examining in this workshop could include: .ZIP, .PDF, .TXT, .CSV, .TSV. .XLS, .XLSX, RDF, .nt, XML (TEI, ALTO and bespoke), .JSON, .JPG, .JPEG, .TIFF and .WARC
Please ensure you are able to read these files on your device before the workshop if you are interested in exploring them during our session.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Digital preservation is not simply a technical challenge.
It requires an ongoing and typically recursive series of actions
and interventions throughout the lifecycle, to ensure
continued & reliable access to authentic digital objects, for as
long as they are deemed to be of value.

Whenever I give a talk about digital preservation, I more often than not start with this slide. Because our digital collections are at the heart of our national digital library, and at the heart of what we do in digital preservation.
Our collection is amazing. It’s so diverse. And it’s huge. We have several petabytes worth of collection content, comprised of millions and millions of unique files. These files contain content ranging from legacy demo discs and decades worth of conference proceedings, to geospatial datasets, electoral registers, digitised newspapers, manuscripts and books, ebooks, ejournals, sound archives, moving images, e-theses, even the UK web archive. The list goes on and on.
But how do we go about preserving all of this content? What risks must we mitigate in order to ensure persistent and long term access? How do we optimise workflows for efficient preservation at this type of scale? How are the needs of digital content different from analogue content? Who should be responsible for digital preservation? What’s the strategy? What’s the policy? What’s the system? What are the challenges?
Well actually, we know the challenges quite well. We spell them out in our digital preservation strategy, which also outlines HOW we’ll go about preserving our digital collections and sustaining their value - not just for this generation of researchers, but also countless future generations.
Now, you might recognise this. It’s a BBC Micro. They were very popular in the 1980s and could be found in several classrooms across the UK, even the occasional home. But no longer – these are technologically obsolete. This technology is outdated, has been surpassed, and is no longer supported.
Technological obsolescence is often regarded as the greatest threat to digital material. This is because as technology changes, it becomes increasingly difficult to reliably access content created on and intended to be accessed on older computing platforms. Yet this is just the long term view: in the shorter term we must also consider everything from media integrity and bit rot to digital rights management and metadata.
Other notable differences between analogue and digital content further add to the challenge:
Fragility of storage media: Storage media degrades. CDs, tapes, discs - they don’t always age as well as expected. This degradation can sometimes have catastrophic effects upon the integrity of the content. Bit rot, for example, can prevent files from rendering correctly if at all; this can happen with no notice and within just a few years, sometimes less, of the media being produced. Now if you’re interested in seeing how this can manifest, take a look at @flipbitbot on Twitter
Integrity & validation: It’s much easier to make unnoticed changes to digital content than to traditional objects. Just think how easy it is to change a word in a file, or to move an object around on a page. And just think as well about changes that can occur when you update a file from one version of a format to another – these happen automatically. These are changes which may affect the authenticity and integrity of the object, and impact on their reusability, particularly for scientific research. Malicious change must be prevented and appropriate change managed;
Proactive Lifecycle management: We need to proactively manage digital content throughout the entire lifecycle. Ongoing technological advances and the fragility of digital content require preservation actions to be taken much earlier in the lifecycle than for traditional collections, and at a much greater frequency. A lifecycle management approach is needed to ensure appropriate actions are taken, and in good time, in order to avoid damage or loss.
Ultimately, dgital preservation is not simply a technical challenge.
It requires an ongoing and typically recursive series of actions and interventions throughout the lifecycle, to ensure continued & reliable access to authentic digital objects, for as long as they are deemed to be of value. It’s not just about technology. It’s also about people. It’s about policy. It’s about resources. It’s about the collections. It’s about research – because we are always shooting at a moving target, and digital preservation is still an emerging discipline. And it’s about a strategy that brings all of that together to ensure persistent access over time.
Our current digital preservation strategy is very much focused around the replacement of our digital repository system. We currently manage content in a four node replication system that we built and developed ourselves. We’ve recently procured a new system called Libsafe, and we’re in the process of working out how to migrate our collections into this new system and make our workflows more efficient.
Alongside Libsafe, we’ll be running a platform called IPS, which stands for the Integrated Preservation Suite. IPS is one of the products of our digital preservation research programme. It’s a new system tat will support preservation planning at scale. Designed to interface with any repository system, it comprises a technical registry, a software repository, and a policy planning database, all accessed by a Preservation Workbench. When a risk alert is received, we can spring into action to initiate and implement a preservation plan across all of the affected files – however many thousand or million that might be! - to mitigate that risk and maintain reliable access to our collections.
Another fantastic research project we have underway is called Flashback. This is a project to safeguard over 100,000 legacy disc-based items that the Library originally acquired on handheld media, many before the turn of the millennium, and process them for ingest to our new repository. Ultimately we want to make them available in our reading rooms using a scalable emulation-based system. We have a little way to go before that’s ready, but we’re on the way.
And that’s me done. This has only been a very quick introduction into digital preservation. There’s so much more I could have said. But I hope we’ve piqued your interest. If you want to know more, come and fund us over the break.
