I spent most of my time this week getting back into the development of the front-end for the Books and Borrowing project. It’s been a long time since I was able to work on this due to commitments to other projects and also due to there being a lot more for me to do than I was expecting regarding processing images and generating associated data in the project’s content management system over the summer. However, I have been able to get back into the development of the front-end this week and managed to make some pretty good progress. The first thing I did was to make some changes to the ‘libraries’ page based on feedback I received ages ago from the project’s Co-I Matt Sangster. The map of libraries used clustering to group libraries that are close together when the map is zoomed out, but Matt didn’t like this. I therefore removed the clusters and turned the library locations back into regular individual markers. However, it is now rather difficult to distinguish the markers for a number of libraries. For example, the markers for Glasgow and the Hunterian libraries (back when the University was still on the High Street) are on top of each other and you have to zoom in a very long way before you can even tell there are two markers there.
I also updated the tabular view of libraries. Previously the library name was a button that when clicked on opened the library’s page. Now the name is text and there are two buttons underneath. The first one opens the library page while the second pans and zooms the map to the selected library, whilst also scrolling the page to the top of the map. This uses Leaflet’s ‘flyTo’ function which works pretty well, although the map tiles don’t quite load in fast enough for the automatic ‘zoom out, pan and zoom in’ to proceed as smoothly as it ought to.
After that I moved onto the library page, which previously just displayed the map and the library name. I updated the tabs for the various sections to display the number of registers, books and borrowers that are associated with the library. The Introduction page also now features the information recorded about the library that has been entered into the CMS. This includes location information, dates, links to the library etc. Beneath the summary info there is the map, and beneath this is a bar chart showing the number of borrowings per year at the library. Beneath the bar chart you can find the longer textual fields about the library such as descriptions and sources. Here’s a screenshot of the page for St Andrews:
I also worked on the ‘Registers’ tab, which now displays a tabular list of the selected library’s registers, and I also ensured that when you select one of the tabs other than ‘Introduction’ the page automatically scrolls down to the top of the tabs to avoid the need to manually scroll past the header image (but we still may make this narrower eventually). The tabular list of registers can be ordered by any of the columns and includes data on the number of pages, borrowers, books and borrowing records featured in each.
When you open a register the information about it is displayed (e.g. descriptions, dates, stats about the number of books etc referenced in the register) and large thumbnails of each page together with page numbers and the number of records on each page are displayed. The thumbnails are rather large and I could make them smaller, but doing so would mean that all the pages end up looking the same – beige rectangles. The thumbnails are generated on the fly by the IIIF server and the first time a register is loaded it can take a while for the thumbnails to load in. However, generated thumbnails are then cached on the server so subsequent page loads are a lot quicker. Here’s a screenshot of a register page for St Andrews:
One thing I also did was write a script to add in a new ‘pageorder’ field to the ‘page’ database table. I then wrote a script that generated the page order for every page in every register in the system. This picks out the page that has no preceding page and iterates through pages based on the ‘next page’ ID. Previously pages in lists were ordered by their auto-incrementing ID, but this meant that if new pages needed to be inserted for a register they ended up stuck at the end of the list, even though the ‘next’ and ‘previous’ links worked successfully. This new ‘pageorder’ field ensures lists of pages are displayed in the proper order. I’ve updated the CMS to ensure this new field is used when viewing a register, although I haven’t as of yet updated the CMS to regenerate the ‘pageorder’ for a register if new pages are added out of sequence. For now if this happens I’ll need to manually run my script again to update things.
Anyway, back to the front-end: The new ‘pageorder’ is used in the list of pages mentioned above so the thumbnails get displaying in the correct order. I may add pagination to this page, as all of the thumbnails are currently on one page and it can take a while to load, although these days people seem to prefer having long pages rather than having data split over multiple pages.
The final section I worked on was the page for viewing an actual page of the register, and this is still very much in progress. You can open a register page by pressing on its thumbnail and currently you can navigate through the register using the ‘next’ and ‘previous’ buttons or return to the list of pages. I still need to add in a ‘jump to page’ feature here too. As discussed in the requirements document, there will be three views of the page: Text, Image and Text and Image side-by-side. Currently I have implemented the image view only. Pressing on the ‘Image view’ tab opens a zoomable / pannable interface through which the image of the register page can be viewed. You can also make this interface full screen by pressing on the button in the top right. Also, if you’re viewing the image and you use the ‘next’ and ‘previous’ navigation links you will stay on the ‘image’ tab when other pages load. Here’s a screenshot of the ‘image view’ of the page:
Also this week I wrote a three-page requirements document for the redevelopment of the front-ends for the various place-names projects I’ve created using the system originally developed for the Berwickshire place-names project which launched back in 2018. The requirements document proposes some major changes to the front-end, moving to an interface that operates almost entirely within the map and enabling users to search and browse all data from within the map view rather than having to navigate to other pages. I sent the document off to Thomas Clancy, for whom I’m currently developing the systems for two place-names projects (Ayr and Iona) and I’ll just need to wait to hear back from him before I take things further.
I also responded to a query from Marc Alexander about the number of categories in the Thesaurus of Old English, investigated a couple of server issues that were affecting the Glasgow Medical Humanities site, removed all existing place-name elements from the Iona place-names CMS so that the team can start afresh and responded to a query from Eleanor Lawson about the filenames of video files on the Seeing Speech site. I also made some further tweaks to the Speak For Yersel resource ahead of its launch next week. This included adding survey numbers to the survey page and updating the navigation links and writing a script that purges a user and all related data from the system. I ran this to remove all of my test data from the system. If we do need to delete a user in future (either because their data is clearly spam or a malicious attempt to skew the results, or because a user has asked us to remove their data) I can run this script again. I also ran through every single activity on the site to check everything was working correctly. The only thing I noticed is that I hadn’t updated the script to remove the flags for completed surveys when a user logs out, meaning after logging out and creating a new user the ticks for completed surveys were still displaying. I fixed this.
I also fixed a few issues with the Burns mini-site about Kozeluch, including updating the table sort options which had stopped working correctly when I added a new column to the table last week and fixing some typos with the introductory text. I also had a chat with the editor of the Anglo-Norman Dictionary about future developments and responded to a query from Ann Ferguson about the DSL bibliographies. Next week I will continue with the B&B developments.
