Using CFEO
Browsing, viewing and comparing images
Browsing the database is accomplished using the tree display in the browse pane. The tree display contains a complete listing of the database contents. When you first open the database, the tree is totally collapsed. To find the piece you are interested in, simply look down the list, using the scrollbar if necessary, and expand the tree to view more detailed information of the piece concerned. You can expand as many entries at a time as you like, clicking on the 'plus' icon to do so.
The tree display is quite complex: it contains a great deal of information in a very condensed form. Once you are familiar with it, however, it should be relatively quick to find what you need. In the following set of screenshots we have illustrated the process of finding a piece, expanding the tree display, and exploring the available information.
Step A
The first part of the process is finding the right piece in the list in the browse pane. Note that the list contains a large number of items; since not all will fit on the screen, you may need to use the scrollbar on the right to find the item you want. In this example, we are interested in the Variations Op. 2. Click the 'plus' icon [1] to the left of the entry in the tree display. The display opens and an animated icon [2] appears whilst the data is loaded in real time from the database (note that this can sometimes take a few seconds depending on the complexity of the work).
Step B
Once the data has loaded from the database, the tree expands, as shown in the screenshot above, to reveal the next level of information. Listed beneath the title of the work you will see [3] a link to display the Publication history of the piece (available for most works in the database), which will appear in the display pane to the right when the link is clicked. Beneath this further links to the source information texts for each of the available editions are listed [4]. In the example shown above there are four sources (French First Edition, Second French Edition, Austrian First Edition, and English First Edition), each of which has a source description entry: clicking the links displays the information in the display pane.
Beneath the publication history and source information links is a listing of the constituent 'work components' (in the example above, Introduzione, Thema etc., in addition to Front matter) [8], each of which can be expanded. To the right of this display is a grid of 'source icons' which are codes designating the available sources in the database [5]. In the above example, the codes are F, F2, A and E (French First Edition, Second French Edition, Austrian First Edition, and English First Edition). (A full list of these and other abbreviations is available in the User Guide.) Note that the icons are shown in colour where a given component exists for a specific source [6], or greyed out if that component is absent from the source [7]. In the example above, the 'Front matter' work component exists in three of the four sources (F, A, E) but not in F2; similarly, 'End matter' is found in F and E but not F2 or A.
Step C
Within each work component is a further listing showing the available intrumental (or occasionally vocal) parts: again, to view this information the list may be expanded at the appropriate point either by clicking the 'plus' icon (which displays the work components for the first of the sources listed), or by clicking the 'source icon' corresponding to the edition in which you're interested. In the example above we have chosen to see more information about the 5th variation (labelled 'Var. 5'), and the Austrian edition has been selected. You can switch between the available editions at any time by clicking on a different 'source icon' (so, for example, we could click F2 to explore the contents of the Second French edition).
This particular component of the piece contains a piano part. Expanding this using the 'plus' icon reveals links to images of the scanned pages from the CFEO score. Each image is designated by means of the relevant page number in the actual score and the corresponding bar range on that page. Clicking the page/bar designator [9] will bring up a full-sized image of the page in the display pane to the right; alternatively, as you place your mouse over the page/bar designator, a set of three 'image comparison icons' appears to the right of the list [10, 11, 12]. These icons allow you to split the display pane into two or three parts, as a result of which you can display and compare up to three discrete images at a time. Clicking the first icon [10] will display the image in the top part of the display pane; the middle icon [11] displays the image in the centre of the pane; and the final icon [12] displays the image in the bottom of the pane.
In the example above, we could view both of the listed images (pages 16 and 17) first by moving the mouse pointer over the 'p. 16' label to reveal the image comparison icons; then by clicking the left icon [10] to show the image in the top of the display pane; and finally by moving the mouse over the 'p. 17' label and clicking the middle [11] or bottom [12] icons.
In this way it is possible to compare images from multiple sources of the same work or even from totally different works; one can also compare select passages from within a single source. If for example we wanted to compare bars 192–200 in the Austrian First Edition of the Variations Op. 2 with the corresponding passages in the French and English First Editions, we would:
- expand the list to reveal the display shown in Step C above, and choose to view the image of p. 16 in the top of the display pane (by clicking icon [10]);
- select the French edition by using the 'source icon' and then repeat the above procedure, choosing to display the image in the centre of the display pane using icon [11];
- repeat this again by choosing the English edition and opening the corresponding image in the bottom of the display pane using [12].
When you want to compare images across multiple works, across multiple editions, or within a single edition, simply expand the tree to find the images you're interested in and use the image comparison icons to display them appropriately.
