0. The aim of this communication
In 2007 the collection management department of ICP was restructured. At that time several
shortcomings were detected. However, it was not until last year that we started to implement
some solutions. One of these new projects is the management of the locations, which we try
to improve with the introduction of new technologies.
We have just begun, we are not experts, but we think it’s interesting to share the project’s
conception and the methodology used.
Often small museums (like ours) have not the resources to solve some problems. These are
common in many centers. So we think to share of our short experience will help other
institutions to solve the problem faster.
1. Presentation of the ICP
First of all I would like to present our institution and our work. I think it’s important because
the majority of the participants in the ERC belong to the world of art. So please, let me
introduce you into the world of fossils.
a. What it is
The Institut Català de Paleontologia (ICP) is a private foundation created in November of 2006.
It belongs to the local government of Catalonia (research department, not culture) and it is
heir of an old Institute created in 1969.
As a center of reference in research, conservation and diffusion of the paleontology of
vertebrates in Catalonia (Spain), the ICP aims to promote research and conservation of the
paleontological heritage at an international level and allow the efficient transfer of knowledge
to society.
We carry out all the stages of paleontology from the finding, excavation and preparation of a
fossil to its conservation, study and publication of results in scientific magazines and to its
exposure in the mass media, exhibitions and museums.
b. Where it is
Due to the expansion experienced over the last years (nowadays we are 50 people) our
Institute has four sites. The research departments and preparation labs are located in the
University (UAB) and the Museum and warehouses are located in the city of Sabadell.
2. The collection of the ICP
2.
Our collection is used basically to research and, sometimes, to exhibit what is investigated. It
includes fossils, current material as well as the moulds and casts of different pieces.
a. How many pieces it has and from where they come
It contains more than two hundred thousand specimens that are between 240 million years
and 10,000 years old. It is considered one of the most important collections of fossil
vertebrates in Europe.
It can be divided into: macrofossils, with almost sixty thousand prepared and catalogued
pieces; and microfossils, with more than forty thousand pieces, mainly mice and shrew teeth.
The origin of the pieces is diverse. We have materials from the Iberian Peninsula, but there are
also specimens coming from France, North Africa and the United States.
b. Annual rate of entries
How do fossils arrive to ICP? As in other countries, Spain has an important regulatory
framework which governs the proceedings on cultural heritage. These laws require that all
construction activities carried out on archaeological or paleontological sites should have a
technical control. They also mark that all pieces appeared should be deposited in a public and
monographic museum. In our case, all the excavated fossils in Catalonia are deposited in our
center, which is responsible for their preservation.
Each year, about 22.000 new fossils arrive to the ICP. For that reason we have a specific
department to manage these inputs of material, including the transport and inventory from
the site to the centre.
c. Consultations and movements per year
All these fossils are stored in a special warehouse. From there, they are transported to the
preparation lab, where the sediment that surrounds them is removed and the fossil is
consolidated. Now, they are ready to be catalogued and studied.
The main use of our collection is the research. Scientists from Spain, Europe and other
continents come to Sabadell to study our fossils.
We have an average of 200 requests per year, including loans and consultations. This means
that there is a movement of about 8000 fossils per year, regardless of the inputs of new
materials.
3. Main problems of the collection of the ICP
Currently, the departments related with the collection include 11 people (curators and
managers). This number is not enough to standardize the collection protocols and to solve the
problems accumulated over 50 years. The main problems we have are:
a. In terms of conservation
We need to improve the screening of the collection to identify problems of conservation. We
also need time and people to solve each problem identified.
4.
Second, because our collection staff do not have adequate knowledge to evaluate the market
offerings.
In our case it was very important the role of an external company, specialized in process
analysis and in software implementation. This company is CCQ and they had the time and the
knowledge to search solutions for us.
6. Looking for solutions
a. Analysis of procedures of the Collection Department
Its first step was to analyze the work of collection area. What we did and how we did it. This
analysis allowed having an objective view of our procedures and hot spots in the collection
management. To do the analysis, CCQ met with all members of the department and
interviewed us. During these meetings, they identified the points for improvement.
b. Improvement options: staff increasing versus new technologies
The solution that seems the simplest to solve the locations problem is hiring more staff.
However there are options with a lower cost and higher efficiency.
In Spain, the gross cost of hiring a full‐time technician is about 36.000 € per year. Normally it is
possible to hire staff for some months, but not permanently. This means investing time in
training again and again to different people (which finally left the museum for a more stable
and better paid work).
If we can introduce a system capable to improve the management of the locations with the
current staff, the investment (economic and psychological) will be lower.
In our case, the introduction of a new technology has one con: the lack of background.
c. Our choice: new technologies
Despite this, our choice was the introduction of new technologies to improve the locations
management.
7. New technologies in the market: different options
When we are looking for solutions to improve the detection of a fossil in the store, there are
basically two options in the market: barcodes and RFID.
a. Barcode
As you know, there are two major types of barcodes: linear and bi‐dimensional.
The most common type of linear barcode is EAN: European Article Number (now called
International Article Number). Normally it presents 13 digits which codify different
information.
In the case of bi‐dimensional codes we can find the data matrix and the QR code.
5. In both cases (linear and bi‐dimensional), the main handicap is the need to have “visual
contact” between the tracker and the label.
For us, this is a great disadvantage because the storage of fossils does not allow this “visual
contact”. So, barcodes are not useful to find a needle in a haystack!
b. RFID
RFID is a system of storing and remotely retrieving data, using trackers and labels called TAGs.
The main purpose of RFID technology is identification and tracking of objects via
electromagnetic waves.
Each tag consists of a small chip, which stores all the information, and a big antenna, which
transmits and receives this information by radiofrequency.
Essentially there are two types of tags: active (which contains a battery and can transmit
signals once an external source has been successfully identified) and passive (which have no
power source and require an external electromagnetic field to initiate a signal transmission).
The problems may have RFID technology:
‐ The presence of metal, which bounces the signal
‐ The presence of liquid, which reduces the signal
‐ A bad use, which can break the chip
‐ The presence of potent frequency inhibitors CLIC
As environmental conditions, RFID technology does not work at temperatures above 70oC and
below ‐20oC. (I think any person should work under these temperatures…)
The main advantage for us is that it does not need visual contact between tracker and tag.
In addition, passive labels do not require power and are cheaper than active ones.
8. Providers
a. Searching companies
The main problem when we have to choose a new technology:
‐ The selling company has tightly controlled the sale process, but the buyer (the museum) is
almost neophyte.
A consulting company helps the buyer TO CHOOSE what he buys (not to buy what the seller
wants).
In our case, CCQ made the following steps to find companies:
‐ Internet tracking
‐ Finding references through friendly channels
‐ Contacting with companies that already use the product successfully
7. ‐ Test: from November 25th to December 3rd
‐ Validation: until December 17th
‐ At the end of 2010, the project should be finished.
b. Partners of the project
As we have already said before, there was no known reference to the use of passive RFID in
control of museum collections. For this reason it was necessary to develop a product
(software) specific for the ICP. We think a customized product has a great disadvantage: a
future client’s weakness against the provider.
Because of the location problem is common to many museums, we propose to develop a
standard product applicable to other collections. In this case, our role is to be the first test
institution.
Saident had to decide if it was interesting to host this project as a new line of business growing
and opening a new sector: the museums. The consulting company’s experience was very
important to convince Saident that museums are an active sector in full development and
growth in relation to new technologies. Finally, Saident accepted.
So, this project is developed by three partners:
ICP: contributes expertise on the collection.
Saident: contributes expertise on RFID implementation.
CCQ: contributes expertise on general assessment in software implementation.
c. How to insert information in a tag?
When we create a new register in the database, we must record this information in a tag.
How?
Problems with the company that develops collection software do not allow integrating RFID in
this software. So, we have a small application that acts as a bridge between the database and
the tag.
We have a USB device connected to our computer, on which we place the new tag. With this
specific software, we do record the information of the new fossil. This information is
transmitted from the database to the TAG by radiofrequency.
d. What types of RFID tags we use?
We essentially will use three types of tags, all passive ones. These types depend on the size of
the material to control.
In our collection we have microfossils, which are stored individually above lego pieces (near to
60.000 pieces); CLIC and macrofossils (near to 70.000 pieces), which have a specific label and
they are stored in plastic boxes CLIC (3.000 boxes). So, we are interested in controlling the lego
pieces, the macrofossils labels and the boxes.
e. How we read the information in an RFID tag?
8.
The first decision was to use UHF frequency, which brings many advantages to the project
(increased the range and the speed reading).
To read the tag information we use a portable tracker, like a PDA. Before to start, we must
synchronize it with the database, to collect the latest changes.
Once synchronized, we can begin the process of inventory or search by choosing one of two
options in the tracker.
‐ If we make a total inventory: the tracker begins to read the pieces detected. We can stop at
any time and keep the information already checked, allowing us to continue at another time.
‐ If we make a partial inventory: first we must choose the search criteria. Once applied, the
tracker will check the collection letting us know when it finds something sought.
In both cases, the tracker contrasts real information with database information. Upon
completion, it generates a report with the errors detected.
f. Initial handicap.
For the moment, due to problems generated by software used for database (created by a
different company), data communication goes only in one direction: from the database to the
RFID software. Never in the wrong way round.
This means that we cannot correct errors found during the inventory, something that would be
very useful to save time.
g. Cost
The main cost of RFID technology is the tags. For example, we need more than 100.000 tags.
But it is not necessary to buy all them at once. We can make a plan and see how fast we will
use them and then, to buy as we need.
Small tag: 0,12 €/UNIT
Fossil and box tag: 0,16 €/UNIT
The software cost is for the annual license, depending on the number of simultaneous users.
10. Work done to date and next steps
a. Contract signing and first tests
At this time ICP has signed the contract with Saident and development phase has begun. As we
explained, it is expected the application will be running at the end of the year.
b. Project development and evaluation
In the early months of 2011 we will evaluate the project and begin to develop some
improvements (such as bidirectionality tracker‐database).
11. Conclusions
9.
‐ Because of the problems accumulated over 50 years and the current rate of requests, we
have the need to find a specific solution for managing the locations.
‐ We opted for the new technologies in order to make more efficient the work of our staff.
‐ For us, new technologies are cheaper than hiring.
‐ Due to the impossibility of having “visual contact” between the label and the reader, we
choose the passive RFID instead of barcodes.
‐ We are developing a standard product that can be applied to other institutions, with the aim
of creating an important customer lobby and not be alone in front of the provider.
‐ This product, under development, allows full and partial inventories and also to make specific
searches by various criteria.
‐ This process of analysis and solution would not have been possible without a consulting
company specialized in new technologies. We believe it is important that museums
professionals have the advice of other specialists groups.
