QR codes: do they provide the missing link between the physical and the digital? – Tristan Badham
Received the VALA Travel Scholarship to see how QR codes were being used in libraries, their implementation, reception from users and staff, further ideas etc.
QR codes are 2 dimensional barcode when scanned by a mobile device, you get linked to the resource the creator intended. Could be website, email address, phone number, coordinates on a map. You need a mobile device, with a camera, an Internet connection and QR code reader (an app) to make use of QR codes.
Being used a lot in advertising, real estate signs etc.
How they can benefit libraries:
act as a bridge between the physical and the digital
make access to information and resource easier
Providing information at the point of need:
video guide on how to use the print management system
a map of the library layout
library audio tours
Catalogue records, with links to specific location information
QR codes within the collection, to link to online resources – particularly to the mobile version of them.
Social media – can communicate your library presences.
Contact the library and research help – particularly SMS reference services.
Other non-library uses included:
videos by curators talking more about the art work being viewed
Powerhouse Museum has built an app which the QR code refers to when scanned – each specific piece links to a specific page
Cheap and relatively easy to implement – time is in the staff and sign creation – also have good tracking
Marketing appeal – makes the library look tech savvy
Device can’t read the code – too big or too small or incorrect lighting
Used the wrong way
People don’t know what they are or how to use them
Devices need a QR code reader which means downloading an app….
The more content your destination has, the more complicated the QR code, which loses pixilation in resizing. If that is the case, use a URL shortener first.
So are they really all that good?
They are worth exploring as a useful technology, especially within the broader context of the move to mobile technologies
one tool among many
could complement rather than compete with other technologies
Awareness of the codes is high amongst young people, even if they don’t know what they are called.
QR codes could burst on the scene, but if they are used in the wrong way, they may disappear. (bit like Brendan Fraser as an actor).
Hacking the nation: Libraryhack and community-created apps – Margaret Warren and Richard Hayward
LibraryHack was created to foster re-use library data – a direct result of the NSLA Re-imagining libraries vision. QSL was responsible for Project 5 – community created content. It aims to make real the ability to help people to find, remix and create new content. Library hack was in four parts.
1. Release of library data and digital content for re-use.
Data was to be made available on data.gov.au, so to ensure the data was discoverable where other public data was available and to add a presence for cultural data. All ten participating libraries placed their data in this central location. Fifty-three datasets were added, primarily images, but also search transaction logs, music and art. Data was able to be licensed for re- use, using Creative Commons. Copyright is an important consideration. Discovered that having geo-spatial data included, made the data more popular and re-usable and that most library formats are not re-user friendly. If we want to encourage more photo mash-ups, we need to make high resolution images publicly available.
Interestingly, Ancestry has taken on the public data and made good use of it.
Discovering the sorts of things that people would be interested in
Days for people interested in working with the data, to come and talk to the content specialists and to find out more about the datasets.
Offered a range of learning opportunities, focused on different topics, including animation and more on how to mash-up this data. Videos are still available at QUT for anyone who is interested.
Received 168 entries for the competition, as well as people creating new apps that were never entered into the competition.
Judging criteria: use of data/digital content, originality, quality, usefulness. Judging panel came from NSLA libraries.
Ideas category winner – Discovery by Diana Iles – included maps, images, manuscripts and map overlay integration. It delivered a visual message, but can be interactive when properly encoded with geo-spatial data.
Apps category winner – talking maps by Michael Henderson – walking West End multimedia tour (Brisbane suburb), custom built geographic interface, talkingmaps.com website, can listen to audio and explore images on the walk
Photo mashups category: Reflection of Time by Andrew Young – included historical images, with reflection of the artists own original work of a contemporary version of the same scene incorporated into it.
Digital media mashup category – Glorious image viewer by Mark Balandzic – projection of historical images on a variety of rotation lamps.
Collaboration was the key, between hackers and between them and the library. Mostly it was fun.
Also resulted in great staff engagement.
Next: More. Better. Easier. Collaboration.
Harvesting and semantically tagging media releases from political websites using web services – Peter Neish
Why are they interested in media releases?
Play an important part in political process
establish a party’s position on an issue at a particular time
often used in time urgent reference request
may go back many years (library has database back to 1992)
Number of political media releases released in Victoria has risen from just over 1000 in 1992, to over 6000 in 2009 and 5000 in 2010. The government puts out a lot more media releases than the opposition. The government keeps it own databases of these media releases. If it was online, the library stopped duplicating that work.
Due to the potential loss of this data when a change of government occurs, the decision was made to begin harvesting this data on the go. The aims of the project were to automate the process, combine the different databases together and to examine the possibility of automatically applying tags to media releases using web services.
Part 1 – Automation
Key was RSS
Political parties have websites, which had RSS feeds, which were used as a standard input to software.
Built, in Java, a servlet which polled and returned the data from the political parties website – put the full-text and its associated metadata into the library database. It also produced and saved a pdf version of the media release.
It works, having harvested over 11000 media releases since July 2010, freeing up 2 days of staff time per week. Problems include having non-standard content in feeds (eg. dates), which they addressed with Yahoo Pipes and website’s changing their structure or CMS.
Part 2 – Semantic tagging
Manual tagging was no longer viable. After examining many options, went with Open Calais – from Thomson Reuters. Although business focused, it matched up with the type of data they had, gave a good number of tags (around 20), minimal false matches, good documentation sand community and generous limits on API calls. Unfortunately, their algorithm is a closely kept secret and not as much development is happening. Check out an example at http://viewer.opencalais.com/.
User Interface – did some useful user testing which helped inform the creation of the interface.
Review – of tagging – about 85% were correct – 4% were incorrect, 6% repeated and 5% redundant. One of the things they always got wrong was Victoria which it placed in the Seychelles – very frustrating.
Linked Data – get the info back in JSON and RDF. It links to its own ontology – which means that limited classes for government.
Media releases are now available as they are released – no backlog. Data is enriched by tagging and in future will link to other databases in the Linked Data ecosystem.
