 In both cases, the function must have the same name `problem_name` as the file.
 * When submitting a problem, please pay particular attention to the documentation. We would like to gather as much information as possible on the provenance of problems, other problem sets where the problems are present, and general information on the problem. 
-The documentation should be added to the file in the `PureJuMP` folder.
+The documentation should be added to the corresponding fields in the `Meta` folder.
 * New problems can be scalable, see [ADNLPProblems/arglina.jl](https://github.com/JuliaSmoothOptimizers/OptimizationProblems.jl/blob/main/src/ADNLPProblems/arglina.jl) and [PureJuMP/arglina.jl](https://github.com/JuliaSmoothOptimizers/OptimizationProblems.jl/blob/main/src/PureJuMP/arglina.jl) for examples. In that case, the first keyword parameter should be the number of variables `n::Int` and have the default value `default_nvar` (constant predefined in the module). If your problem has restrictions on the number of variables, e.g., `n` should be odd, or `n` should have the form `4k + 3`, then, instead of throwing errors when the restrictions are not satisfied, you should instead use the number of variables to be as close to `n` as possible. For example, if you want `n` odd and `n = 100` is passed, you can internally convert to `n = 99`. If you want `n = 4k + 3`, and `n = 100` is passed, then compute `k = round(Int, (n - 3) / 4)` and update `n`.
 * A first version of the `meta` can be generated using `generate_meta`. A `String` is returned that can be copy-pasted into the `Meta` folder, and then edited.

+The `:lib` column records membership in named optimization test-set collections.
+Each entry is a comma-separated list of `"Collection:ID"` pairs; an empty string

+`OptimizationProblems.LIB_REFERENCES` provides the canonical BibTeX entry for

+`include_lib_refs = true` (the default).

+Problem :
+The clamped plate problem (Strang, Nocedal, Dax)
+The problem comes from the discretization the following problem
+in mechanics:  a plate is clamped on one edge and loaded on the
+opposite side.  The plate is the unit square.
+In this version of the problem, the weight WGHT is entirely put on the
+upper right corner of the plate.
+The plate is clamped on its lower edge, by fixing the
+corresponding variables to zero.

+Description:   These data and model are described in Daniel and Wood
+               (1980), and originally published in E.S.Keeping, 
+               "Introduction to Statistical Inference," Van Nostrand
+               Company, Princeton, NJ, 1962, p. 354.  The response
+               variable is energy radieted from a carbon filament
+               lamp per cm**2 per second, and the predictor variable
+               is the absolute temperature of the filament in 1000
+               degrees Kelvin.

-Description:   These data are the result of a NIST study involving
-               ultrasonic calibration.  The response variable is
-               ultrasonic response, and the predictor variable is
-               metal distance.
-
-Reference:     Chwirut, D., NIST (197?).  
-               Ultrasonic Reference Block Study. 
-
-Data:          1 Response  (y = ultrasonic response)
-               1 Predictor (x = metal distance)
-               54 Observations
-               Lower Level of Difficulty
-               Observed Data
-
-Model:         Exponential Class
-               3 Parameters (b1 to b3)
-
-               y = exp(-b1*x)/(b2+b3*x)  +  e

-Description:   The data are monthly averaged atmospheric pressure 
-               differences between Easter Island and Darwin, 
-               Australia.  This difference drives the trade winds in 
-               the southern hemisphere.  Fourier analysis of the data
-               reveals 3 significant cycles.  The annual cycle is the
-               strongest, but cycles with periods of approximately 44
-               and 26 months are also present.  These cycles
-               correspond to the El Nino and the Southern Oscillation.
-               Arguments to the SIN and COS functions are in radians.
